Did think about them. But like you said they reproduce like crazy which can lead to problems.ya did not think you would be able to but still cool creatures I suggest you look into the mourning geckos for the 3g get about 3" and reproduce like crazy
Can flip the tank upright? I have a screen lid. And I like the idea of them.You can house a single green or brown anole on the 10. That would take care of the mourning gecko problem.
You can always fill the 3 with water and go with 2 or 3 dwarf frogs (not reptiles , I know), they are small and fun.
There are also Pygmy chameleons but I’m pretty sure they are really hard to keep and Chameleons can’t be in glass cages.
I don’t see why you couldn’t stand the tank differently. I think they may sell door attachments for the front/top that would work like a screen.Can flip the tank upright? I have a screen lid. And I like the idea of them.
