pet suggestions please if any

[samurai]

I have an 18inch cube tank with front opening doors and mesh lid. I was going to use it for my fire bellieded frogs or newts but these are really easy to keep clean in their large plastic tub homes, so I will keep them in these. Now i'm looking for a new pet, reptile or amphibian that can be kept in a tank this size. I think this tank would be tricky to empty if the base had a lot of water so a land or semi arborel critter would be ideal. Can anyone suggest any pets happy with this size tank, and if they do not require additional heating that would also be a bonus (but not essentail). Pets I have considered so far are, grey or green tree frogs, tomato frogs, green or brown anoles. I want it/them to have enough space to live happily so please keep this in mind, and let me know if too small for those I have already considered.thank you!

Maybe crested geckos?

Personally, I wouldn't keep an adult crestie in a viv any smaller than 45cm x 45cm x 60cm; mine really do make use of all of the space available to them, so I think a smaller viv would be too cramped.

using it for a quarentine tank now, getting 3 more fbt to mix with current one.
