Talking about the crested gecko enclosure size, the best size that suits their needs is between 15-30 gallons vivarium. Baby and Juvenile need much smaller than that because they can’t access their food in a large tank if it runs or hides.

When looking for a crested gecko vivarium size, you should also consider your crestie’s size and age. Many forums and sources claim that these geckos need 10-20 gallon enclosures, but it’s not necessary. Some lizards and reptiles can also feel overwhelmed if there is not enough space for them. 

While you decor their enclosure, the space they get for their activity usually discourages them. Here, You can learn how much space do crested geckos need.

To house one crested GeckoGecko, you should consider getting at least 20 gallons of the enclosure. After properly decorating branches, plants, hides, and rocks, they should have enough space to thrive, run, jump, and hide.

To house more than two or more cresties, you need at least 30 gallons bare minimum size of the tank. 2 crested geckos can be kept in a 20 gallons tank. As you increase the number of crested geckos, you need to add a 50-gallon size or space more for each.

Best Types Of Tank For Crested Gecko


The best material for a crested gecko vivarium is glass. The most significant advantage of keeping crested geckos in a glass tank is that it is easy to clean and can maintain humidity levels better. It is also best for visual display when you house them.

Plus, if you consider housing more than two or more crested geckos, it is also suitable for viewing (due to its transparent sides). The only disadvantage is its high price that can cost you around $100 to $250.

3 Other types of crested gecko tanks you can house in

1. Wood

It’s a perfect option for those who want exquisite housing for their geckos. Finding a wooden enclosure that suits their needs and is easy to operate is difficult to find. Plus, Wood enclosures will be vulnerable to water and heat. Added to that, this kind of habitat can observe water and be difficult to clean

2. Mesh

The lizards and reptiles are housed in tanks made with the mesh that encourages them to jump. Most of the mesh tanks you will find online or locally are tall, encouraging reptiles to climb but not big enough. Please keep them in a mess vivarium because they like climbing.

It isn’t easy to find a 20-gallon long mesh enclosure that is suitable for crested geckos. Plus, the stress and the humidity also need to be considered as a mesh can be prevented.

3. Plastic

Plastic is also a good alternative, but it is not good to maintain the humidity and temperature they need to thrive. Plus, plastic is not durable material from my perspective to house a crested gecko. However, due to its affordable price, it is still good to check. Not all companies make plastic enclosures.

Is 12X12X18 Big Enough For A Crested Gecko?

12X12X18 is enough to house a single adult crested gecko with a mesh screen top. However, keeping them in a 12X12X18 space tank will allow better display. It will also encourage them for activities. Wooden or plastic vivariums should be avoided. Glass tanks are best for crested geckos in most aspects.

Do Crested Geckos Need A 20 Gallon Tank?

Crested Gecko needs a 20-gallon tank. However, their enclosure should have branches and rocks to jump and hide. In the daytime, they like hiding, resting, and sleeping. At night time, they will be most active, jumping, climbing, and running around.

Is A 30 Gallon Tank Too Big For A Crested Gecko?

Sometimes too big tanks also stress a single crested gecko. Keeping a single-crested gecko in 25 gallons or more size tank can stress them out. A 20-gallon size tank is best for a single gecko.

Best Leopard Gecko Setup
