Hi all, I'm looking for suggestions. I have this enclosure called a Zilla Flx (the small one, 12L x 12W x 15H inches). It's got a screen swing open front door, a screen top, and glass all around the rest of it, with a ~4" glass lip at the bottom for water or substrate.

I'm really wanting to fill the bottom with at least a bit of water, preferably 3-4 inches if I could. This tank is arboreal so would be best suited for tree frogs and etc I'd assume... But I'm having trouble finding which frogs or other amphibs would do well with a water-filled bottom, with only a square foot for footprint but a fair amount of height.

Or if anyone can suggest some amphibs that would do well WITHOUT the water-filled bottom, go ahead and suggest them too! I'm willing to adjust my preferences for the sake of the future inhabitants

Thanks!
