12 Best Crested Gecko Terrariums (October 2026) Expert Reviews

The minimum enclosure for an adult crested gecko is an 18 x 18 x 24 inch vertical terrarium, and an 18x18x36 or 24x18x24 model gives an active adult noticeably more climbing room. These lizards are arboreal, so height matters more than floor space, and the enclosure has to hold humidity while still moving air.

That single sentence settles most of the argument, and it is why this roundup skips straight past the aquarium aisle. A crested gecko does not swim, does not need a water feature and does not care what a horizontal tank looks like. What it needs is a tall box with front doors, a ventilated top, solid vertical surfaces to climb and enough humidity to keep the skin from cracking during a shed.

We compared twelve enclosures for this guide, from an 8 gallon glass cube to a 65 gallon PVC vivarium, and read the owner feedback on each one before deciding where they fit. We looked hard at the things that rarely appear on a product page: empty weight, whether the doors stay shut, whether the panel seams leak, and whether the mesh top survives a year of constant misting. Those details decide whether a setup is pleasant to maintain or a chore.

One more thing before the picks. There are three different products sold under the same label. A bare enclosure is an empty glass or PVC box. A kit adds a lamp, bedding, a background panel and a gauge. A fully supplied bundle adds substrate, decor and a cleanup crew. They are not interchangeable, and two of them can add several times the cost of the tank itself. We label every product below so you know which one you are actually buying.

If you want a broader view of housing for other reptiles first, our reptile terrarium roundup covers the same enclosure formats across species.

Top 3 Picks for the Best Crested Gecko Terrariums

Best Crested Gecko Terrariums at a Glance in 2026

Every enclosure below is listed in the same order as the individual reviews, so you can scan this table first and jump to the detail that matters to your setup. The key features column is drawn from each product’s own specification sheet, so treat it as the short version of the review rather than a summary of my opinion.

1. Zilla 11 Gallon Glass Tropical Vertical Kit – the Complete Starter Enclosure

This is the kit we hand to a first-time keeper, and it is the most heavily reviewed enclosure in our group. Everything a new crested gecko owner actually needs on day one arrives in the box: the terrarium, a mini halogen dome with bulb, a rock-like foam background, coconut husk bedding, a humidity and temperature gauge, a feeding dish and a setup guide. Nothing else needs to be ordered before the animal arrives.

Owner feedback keeps landing on the same two things, and both are real. The front-opening glass door makes feeding and spot cleaning quick, and the hinged screen top on top of it means you can reach a gecko that has climbed high without dismantling the tank. Reviewers also point out the 5 inch deep water-tight base as more capable than the specification suggests.

The honest limitation is size. At 12x12x18 this is a juvenile and hatchling enclosure, and treating it as a permanent adult home is the most common mistake we see. Plan on it lasting six to ten months for a fast-growing juvenile, then moving up. We covered a wider general roundup of reptile terrariums if you want to compare formats across species first.

What you get for a first-year keeper

There is a real cost argument here. A bare 12x12x18 glass tank plus a separate lamp, bedding, background and gauge adds up quickly and requires five separate purchases, so the bundled version is often the cheaper path for a first setup.

The switch is speed. Open the box, read the guide, place the animal. For a nervous first-time owner or a gift, not having to assemble a parts list is worth more than the small saving from buying components separately.

When to skip it

Skip it if your gecko is already an adult. At that weight and length, 12x12x18 vertical climb space is tight, and buying it means buying twice within a year.

Skip it if you dislike bundled accessories. You are paying for the foam background and the coconut bedding whether you want them or not, and experienced keepers usually build their own background and substrate instead.

2. REPTI ZOO 24x18x36 Double Hinge Glass Terrarium – the Adult and Large Adult Workhorse

When we want an adult gecko that never has to move again, this is the box we look at first. At 24x18x36 it leaves enough vertical run for tall cork bark, a feeding ledge and a misting headroom, and the 24 inch depth gives a wide planted layout rather than a narrow column. It is a large adult enclosure, not a minimum adult one.

The feature that separates it from a standard glass tank is the switchable side panels. Glass panels and mesh panels swap out depending on the season and how dry the room runs, which solves the ventilation versus humidity problem that most owners argue about. Buyers running adult arboreal species consistently praise the size and the convertibility, and the room you have left for decor after a full planted scape.

Assembly is fast. Owners report two enclosures going together in roughly 30 to 45 minutes, flat-packed in a reinforced box. Front and top doors open separately and the lock keeps both shut, which also stops feeder insects getting out.

How the convertible sides work in practice

Owners who moved up from a 12x12x18 report more activity and steadier feeding after the switch, and the mesh sides are the reason. Swapping a side to mesh raises airflow in a warm room; swapping back to glass slows humidity loss when the apartment gets dry in winter.

Wire and tube inlets are pre-placed so misting lines and heating runs enter from the top rather than through a door gap. That matters more than it sounds, because a hose squeezed through a hinge is where setups leak.

Where the compromises are

Empty weight is 60 pounds, and that is the number that catches people out. It needs two people and a clear path to the stand, and cleaning it means emptying decor, carrying it out and carrying it back.

The side seams are slotted rather than sealed, so heavy daily misting can wick outside the tank. Owners who want a paludarium or waterfall feature epoxy the joints themselves. A few buyers also report the assembled height measuring short of the advertised 36 inches.

3. Zoo Med ReptiBreeze 18x18x36 Screen Cage – the Lightest Adult Option

This has been the default budget arboreal cage for years and it is still the one we recommend for anyone moving a tank alone. At 3.44 pounds empty, it is the exact opposite of the 60 pound glass boxes above, and that difference decides who can realistically deep-clean a setup every week.

Reviewers are consistent about what works. The black anodized aluminum mesh is far sturdier than fabric or plastic screening, it holds live feeders inside, and the bottom door is a genuinely clever touch because you can pull the whole substrate tray level instead of scooping it out with a scoop. The fixed top carries dome lighting fixtures without sag.

The honest complaint is humidity, and it is not a small one. An open mesh cage cannot hold the humidity levels a crested gecko needs on its own, so this is a dry-side-of-the-house answer that needs a mister and a careful position away from drafts.

Where a screen cage makes sense

Quarantine setups, grow-out housing and juvenile racks are where this earns its place. A sick or new arrival needs observation from every angle, and you can reach any part of the cage without shifting the animal’s whole environment.

Apartment and dorm keepers also benefit, because an adult-sized cage you can actually carry between rooms changes how often you do maintenance. Forum keepers mention the mesh holding up well to handling, and the assembly needs only a screwdriver with all hardware included.

Where it falls short

It cannot run a bioactive setup. The unsealed plastic base will not hold wet substrate or a potted plant, and a drip system inside simply wets the floor around the cage. Decide on this one for humidity gear, not for a planted vivarium.

There are no built-in hanging points, so branches have to be zip-tied to the mesh directly. Mesh can tear if a cat reaches through, and some deliveries arrive with bent frame pieces. The top screen also bows under heavier dome fixtures.

4. NEPTONION 12x12x18 Tempered Glass Vivarium – the Juvenile With the Best Cable Management

This is the enclosure we point at when a keeper is running a misting system, a heating setup and a feeding light and does not want three cables squeezed through a back corner. Five closable wire and tube inlets on each side is far more than any other 12x12x18 in this group, and the grommets close around whatever you run through them.

The tempered glass is a real upgrade over standard panes. Owners highlight that it is tougher and holds up better to routine cleaning, and the base is tested to hold four inches of water right up to the glass door, which is a meaningful claim from a manufacturer. The knob lock on the front door also holds against a gecko pushing at it.

It is sold as an empty tank. Decor, substrate, background and lighting are all yours to source, so budget for a second box of items before the animal arrives. Parts are individually replaceable, which is a nice touch when a pane eventually chips.

Why juveniles need a tank like this

Young geckos are the most delicate thing in this hobby. A small crash in humidity shows up quickly as a stuck shed or a weight drop, and glass holds temperature and moisture more consistently than an open cage while a misting system settles in.

Because it knocks down except for the base, you can disassemble it for a deep clean or store it flat between animals. That matters more than it sounds when you are running quarantine cycles on a schedule.

What to watch for

Reviewers report that close to a fifth of ratings sit at three stars or below, with one-star feedback concentrated around packaging and assembly. Inspect the corners and the silicone seams the day it arrives rather than after the gecko is inside.

It is also a 12x12x18, so the same upgrade clock applies. Plan the adult tank purchase in the same year rather than treating it as a final home.

5. REPTI ZOO 8 Gallon 12x12x12 Glass Tank – the Hatchling Grow-Out Box

For a hatchling under about five grams this cube is the right shape. Reviewers like the top opening because feeding is a one-handed job, the security buckle keeps a small gecko from pushing the lid, and the thin wire mesh top passes light well enough for UVB and infrared penetration. The transparent PVC tray at the base is a bonus for a grow-out setup.

We use this as a grow-out box rather than a home. The problem is not quality, it is geometry. A 12 inch cube gives an arboreal lizard a usable vertical run of roughly a foot once the substrate and a hide are inside, and a crestie that size needs a tall environment more than it needs a wide one.

It is a genuine multi-species value box. Buyers list leopard geckos, tarantulas, frogs, hermit crabs and insects. Replacement panels are supplied on request, which is a real benefit when a corner chip happens.

Best used as a nursery box

It pairs well with a small heat mat under one side to create a warm and cool gradient in a tiny footprint. The tray keeps the substrate clean enough to change weekly, which is the main chore with a fast-growing juvenile.

It also solves a problem keepers mention constantly: juveniles are hard to monitor in a big planted vivarium. A clear cube on a shelf next to where you work gives you an easy daily look at body condition and feeding response.

When it is the wrong choice

Do not plan around it for anything past the juvenile stage. Front access does not exist, so large decor changes mean reaching in from the top, which is exactly the approach most owners try to avoid.

Ask yourself whether you will buy a second tank in six months. If the answer is no, start one size up at 12x12x18 and skip the nursery stage entirely.

6. WACOOL 18x18x36 3-in-1 Side Design – the Deepest Bioactive Base Here

The reason we like this one for a bioactive setup is the base. It is rated to hold ten inches of water with a raised frame underneath for a substrate heater, which means a full drainage layer plus substrate plus a planted layer all fit without crowding the climbing space. Most 18x18x24 tanks cannot do that.

At 18x18x36 the vertical format is right for an adult or a large adult, and the side panels assemble three ways: all glass, mesh and glass, or mesh and mesh. Owners use that to shift humidity and airflow seasonally without buying a second tank, and the fine mesh top passes heat and UVB well.

Front doors open independently and a security latch keeps them closed, which is useful with kids in the house and stops feeders escaping. Cable management handles four leads, and reinforced foam packaging plus free replacement of damaged parts reduce the risk of transit damage.

How much substrate depth a bioactive setup needs

A working bioactive enclosure runs drainage layer, substrate and then a planted or decorated top layer. Most of that stack is wasted on a shallow base, because the roots and the leaf litter go where you put them and nowhere else.

This base gives you room to build a hill on one side and a bare glass wall on the other, which is what lets you use live plants and a cleanup crew without the planting medium drying out overnight.

Where it becomes a problem

Weight. A fully assembled 57 pounds with substrate, branches and water is a two-person job, and deep cleaning means clearing the bottom rather than reaching through a front door.

No background is included, and the listing copy is inconsistent about whether this is a 50 or 48 gallon unit. Measure the interior before you buy a fitted background panel.

7. ADVINCI 12x12x16 Aluminum Frame Vivarium – the Lightweight Glass Alternative

Six pounds empty is the headline. Crested gecko and dart frog owners rate this enclosure for value and appearance, and several mention carrying a fully built setup without difficulty, which no glass box in this list can promise at that size. The brushed aluminum rails give it a modern look that reads more like furniture than pet equipment.

It knocks down without tools, and reviewers describe taking it apart and rebuilding it repeatedly during a single build without drama. The top-mounted mesh panel accepts heat lamps and UVB bulbs, the base is a single waterproof tray, and the misting line enters through an integrated tubing pass.

There are two real issues, and both are documented rather than assumed. The door gap of roughly five millimetres is wide enough to let springtails and isopods escape, so a bioactive enclosure needs a foam strip or sealant along the bottom. The listed dimensions are outer, so the interior floor is smaller than the number suggests.

When a light enclosure actually matters

Renters, anyone in a top-floor flat, and keepers who move house every couple of years get the most out of this design. A glass tank you can lift onto a shelf by yourself changes how often a deep clean actually happens.

The detachable design also suits breeders and anyone running quarantine cycles, because you can wipe panels down individually on a counter rather than working inside a frame on the floor.

Trade-offs to plan around

The roughly three inch tray is too shallow for a real bioactive stack. The hollow insulated panels can trap condensation behind them, which is where algae and mould appear in a permanently humid room.

Owners also mention that the latch mechanism can be finicky and has failed over time, and the solid top panel blocks around three quarters of the light, which matters in a planted setup. Swap it for mesh and seal the door gap if you plan to go bioactive.

8. waazoorep 11 Gallon 12x12x18 Glass Tank – the Ready to Go Juvenile Tank

This matches the highest average rating in our group, and crested gecko owners single it out as a genuine home rather than a temporary box. The build quality detail that comes up most is the silicone: cleaner, more evenly applied than comparable tanks, which is the first thing that fails in a permanently humid enclosure.

It arrives fully assembled. That removes the single most frustrating step in buying a knock-down terrarium, and for a first keeper it is worth more than the small saving from building one yourself. A feeding tong is included and the sealed base has a raised bottom for heating equipment.

Front double doors latch, the glass is tempered on all sides, and the removable metal mesh top allows airflow plus UVB and infrared penetration. Owners also comment that the unit has enough heft that a child cannot simply pick it up.

What the rating reflects

Across 161 ratings the 4.6 average is the highest here, and the owner feedback describes it as a strong 12x12x18 for the species. The recurring theme is that crestie keepers set it up as a bioactive enclosure and it holds.

For anyone starting with a juvenile under about 12 centimeters, this is an easy first tank that can be cleaned thoroughly and moved when the time comes to step up.

Long-term drawbacks

The mesh top is the weak point. Owners in tropical setups report rust developing within a year, and constant misting accelerates it. Keep the top dry where you can, and treat it as a consumable part rather than a permanent fixture.

Some units arrive with debris in the base that needs wiping before use, door hinges can sit slightly crooked, and the top mesh is fiddly to remove with unclear controls.

9. REPTI ZOO 18x18x24 Black PVC Tank – the Humidity Retention Leader

This is the enclosure to look at if your room is dry and your gecko is struggling to hold humidity between mistings. Black PVC is a poor conductor, so it holds both heat and moisture noticeably better than glass, and the non-absorbent surface returns to target humidity quickly once you stop spraying instead of slowly leaking it back out.

At 18x18x24 it is exactly the standard adult minimum, which makes it the natural first upgrade from a 12x12x18 juvenile tank. The sliding tempered glass door has a safety lock so you can feed and spot clean without the gecko making a break for it, and the detachable mesh top gives airflow and light penetration.

Owners also mention that the black minimalist styling blends into a living room in a way clear glass does not, and that the panels wipe down easily. The reason buyers pick this over glass is humidity retention, and the trade-off they accept is the viewing area and the finish.

Where PVC beats glass

Humidity recovery time is the honest answer. In a dry apartment, a glass tank can lose the moisture you just misted within the hour, and that constant wet and dry cycle is what causes stuck sheds. PVC slows the loss, so you spray less often and the animal stays in a narrower humidity band.

Heat behaviour matters at night as well. A drop in room temperature moves through glass quickly, and PVC buffers that, which is useful if you are not running a thermostat-controlled room.

What PVC costs you

Durability of the surface. Owners report scuffing and visible wear sooner than glass, and a scratch that would be invisible on a clear pane is obvious on black. Handle the panels with a cloth rather than a sponge with grit on it.

You lose some of the viewing window compared with an all-glass box, and a small share of buyers are disappointed by the finish and hardware durability.

10. OIIBO 30 Gallon 18x18x24 Glass Tank – the First Adult Tank for New Keepers

This is the straightforward 18x18x24 glass answer, and it is the one we recommend to someone moving up from a juvenile tank who wants a familiar format. Full view glass on the sides and front, a removable mesh top, a raised waterproof base that works as either a dry or a rainforest setup, and wire inlets on the top and right for cables and tubing.

Owners who receive an undamaged unit tend to comment that the build quality punches above the price, and several compare it favourably to long-established reptile brands. The double hinge doors open separately, which makes feeding and rearranging decor far less disruptive than a single top-opening lid.

The knock-down design assembles in minutes, and the anti-escape lock is a genuine improvement on cheap sliding-door models. The raised bottom frame fits a heating pad underneath without the glass sitting directly on it.

Why this suits a first adult setup

It is the adult minimum size, and it leaves room in your budget for a misting system, a background and branches. Compared with a premium bundle you are buying the tank and assembling the rest, which is how experienced keepers prefer to do it anyway.

The double hinge doors are the feature first-time owners notice most. A front-opening enclosure means you can reach the animal without lifting a lid over its head, which reduces the stress that causes geckos to drop their tails.

Reasons to pass on it

Transport damage is the most common complaint. Glass panels have shattered in the box or during assembly for a number of buyers, and the plastic door hinges have arrived cracked or misshapen. Order it on a day you can inspect it immediately.

The small door key is fragile and easy to lose, the panel stickers confuse orientation during assembly, and the numerous gaps let small insects and moisture escape, which is a problem for a bioactive enclosure.

11. REPWILD 65 Gallon 24x18x36 PVC Terrarium – the Long Term Large Adult Enclosure

This is the end of the upgrade path. A 65 gallon vertical PVC build at 24x18x36 with half inch panels is a serious long-term enclosure, and owners consistently rate the material thickness first among the reasons to buy. It feels rigid enough that people describe it as solid enough to sit on, which tells you how it handles weight.

The humidity argument is the same one that wins for PVC in general, and for a tall planted enclosure it compounds. More surface area means more moisture loss, and non-absorbent panels give a planted setup a fighting chance. A reinforced mesh top handles airflow and UVB penetration, and a side port hole lets you mount a misting nozzle inside rather than spraying into the room.

Doors are thickened tempered glass with a scratch-resistant coating, which is the one place the material choice of the rest of the tank makes sense. Owners report it surviving clumsy handling during assembly rather than suffering for it.

Who should buy something this large

Keepers with a fully planted enclosure, multiple animals kept separately, or a gecko that spends its day high in the branches. The extra height is what earns the footprint, and the reinforced top is what allows a real light and misting array to sit on it.

It is also a reasonable choice for anyone who expects to keep the same enclosure for a decade. The 15 to 20 year lifespan of the species means the adult tank is effectively a lifetime purchase.

Plan before you buy

Seams are not sealed as shipped. If you want a bioactive or paludarium setup you are adding your own silicone, so build that into your setup weekend. Internal dimensions also run slightly under the listed size, which broke a fitted background for one buyer, so measure first.

Assembly instructions are unclear around the glass doors and trim, there is a laser-engraved logo on the top panel, and at 48.6 pounds you should have a second person on hand for the lift.

12. maiyuolg 16x16x24 Black PVC Front Opening Tank – the Light Dark Enclosure

The logic here is behavioural. Crested geckos are crepuscular, and a fully exposed glass tank means a bright room presses against them from every side for the entire night. A black PVC interior reflects less light back, which is why keepers of nocturnal species pick this format. At 9 pounds it also moves like a cage rather than a tank.

The 16x16x24 vertical format is the smallest adult-capable enclosure in this group, and it is the one place in this roundup where we would push back a little. It works well for a single adult that is not climbing constantly, and the side ventilation plus screen top handle heat and lighting equipment.

Reinforced locking and a modernised front handle are built for daily use, which is the part that matters most in a tank you open several times a day. The screen top accepts heating and lighting gear, and the panels are non-absorbent so humidity recovers quickly after misting.

Dark interior versus glass

Keepers report that the black interior measurably lowers stress compared with all-glass housing, and for a nocturnal or crepuscular species that is the whole point. It also hides water staining and background wear over time, which glass does not.

If your gecko is a hatchling or juvenile that needs to see and be stimulated, the reverse is true and a clear front is the better choice. Darkness helps a stressed adult and does nothing for an active young animal.

Limitations to weigh

Size is the first. 16x16x24 sits under the standard adult minimum, so treat it as a stop for a small adult rather than a final home, and be honest about where the gecko spends the night.

The viewing window is narrower than a glass front, and the PVC and door hardware feel less refined than glass-fronted enclosures. The share of one-star ratings is the highest in this product group, concentrated around finish and hardware durability.

Crested Gecko Enclosure Size by Life Stage

Every conflicting size argument in the keeper forums comes down to a gecko at a different life stage. The ladder below removes the ambiguity. If you are unsure, size up one step rather than down, because a tank that is too large is a cheap problem while a tank that is too small has to be replaced twice.

• Hatchling under 5 g: 8x8x12 or a 12x12x12 cube. Vertical climb is short but cover matters more, and a small box makes daily feeding and monitoring easy.
• Juvenile under 12 cm snout to tail: 12x12x18. This is the workhorse juvenile size and the right answer for the first year for most keepers.
• Adult minimum: 18x18x24. The standard adult minimum for a single gecko, and the size most experienced keepers stop at.
• Active adult: 18x18x36. The vertical run a climbing adult uses at night, and the size many keepers insist on as the true bare minimum.
• Large adult or planted vivarium: 24x18x24 or larger. More depth means a real planted layout and a proper bioactive substrate stack.

Minimum dimensions in centimeters follow the same ladder: roughly 20x20x30 for a hatchling, 30x30x45 for a juvenile, 45x45x60 for an adult minimum and 45x45x90 for an active adult.

How to Choose a Crested Gecko Terrarium

Size and orientation. Height is the dimension that matters for an arboreal species. Check the interior height rather than the listed height, because external measurements include the frame and the top assembly. If a listing gives only outer dimensions, subtract an inch or two before you plan decor heights.

Material. Glass is easy to clean, resists humidity swings less than people expect and gives a full view. PVC insulates and holds humidity better and weighs less, but shows scratches. Acrylic clouds and scratches over time and most experienced keepers have moved away from it. Mesh is light and cheap but cannot hold humidity on its own.

Ventilation and humidity. You need airflow high or low and a humidity band of roughly 50 to 70 percent. A removable mesh top plus side ventilation is the common solution, and a misting system handles the rest. Screen tops dry a setup out fast, so pair them with a humidifier or closer misting head.

Doors. Front-opening doors matter more than most product pages suggest. A top-opening lid means a hand coming down from above, which is the shape most geckos react to. Dual hinge doors that open separately are better still because you can feed without swinging the whole front open.

Empty weight and furniture load. Glass tanks at this size weigh from about 17 to 60 pounds empty and much more when stocked. Check that your stand can carry it, and check the floor if you are not on a desk. This is the single most-skipped criterion in a first purchase.

Bare enclosure, kit or fully supplied bundle. A bare enclosure is a tank only. A kit adds lighting, bedding, a background and a gauge. A fully supplied bundle adds substrate, decor and sometimes a cleanup crew. Bundles are convenient, and assembling the parts yourself usually gives you more usable value per unit.

One gecko per enclosure. Cohabitation is the question we are asked most often, and the short answer is that most experienced keepers house crested geckos individually. If you keep two together, the recommendation is a doubled footprint, separate feeding and a careful eye on dominance behaviour. Size alone does not prevent stress.

Not sure where to start? Tell us your gecko’s age or weight and whether you want a bare tank, a kit or a full bioactive bundle, and the answer narrows to two or three options out of this list.

Setting Up a New Bioactive Enclosure

Once the tank is home, the sequence matters. Do the drainage layer and substrate first while the enclosure is empty and light, then the background, then the hardscape, then the plants, and only then the animal. Misting equipment goes in last and gets sealed around the ports.

• Drainage layer: a coarse material at the base, roughly two inches, to hold water away from the glass base.
• Substrate: a moisture-retentive layer above it, deep enough to support a planted section. Deeper bases let you build a hill on one side.
• Cleanup crew: springtails handle waste on the surface, and isopods such as Rhinocallis and Porcellio work the substrate. Introduce them before the gecko so they establish first.
• Background: a foam, glass or PVC panel that gives a dark surface behind the plant line and hides equipment.
• Branches and ledges: cork bark and branches at three heights, since a climbing gecko uses vertical space rather than a flat one.
• Plants and cover: leaf cover across the top and bottom thirds, so the animal can hide from view whenever it wants to.
• Misting: a top-mounted nozzle inside the enclosure, tested before the gecko moves in, with humidity readings taken at the animal’s height rather than at the top.

Seal the door gaps and the cable ports before stocking anything. A five millimetre gap is enough to lose a cleanup crew, and mist escaping through unsealed seams wets the surface the tank stands on.

Frequently Asked Questions

Conclusion

For most people reading this, the Zilla 11 Gallon Glass Tropical Vertical Kit is the right first buy, because it arrives complete and it is the most heavily reviewed enclosure we looked at. Plan the next step at the same time. When the gecko reaches roughly adult size, move to the REPTI ZOO 18x18x24 black PVC tank for humidity retention, or step straight to an 18x18x36 glass build if you want the animal to stay in one enclosure for life.

That path from 12x12x18 to 18x18x24 to 18x18x36 is how you avoid buying three tanks and losing money on the two you outgrew. If your gecko is already an adult, skip the first step entirely and start at the adult minimum. Our picks for the best crested gecko terrariums will hold up as your gecko changes shape, and you can re-check this list when you are ready to move up.
