Terrestrial reptiles or amphibians for 20 gallon long

Are there any terrestrial reptiles or amphibians that can fit into a 20 gallon long? I'm not interested in any snakes or geckos at the moment. Thanks!

depending on how you set it up there are plenty of frogs that will do fine in there

maybe a small crestie colony? or some anoles.

Leopard geckos would be perfect. They're pretty awesome but if you aren't interested there's. Dart frogs. Pacman frogs. Maybe pixie frog and tomato frog not sure. Cresties are kinda arboreal I believe but I'm sure a 20 gal would suffice. There's also gargoyles. Like previously stated since you aren't into geckos anoles would work. There's also Solomon leaf frogs. Black and yellow toads. Mantellas. That's all I can think of.

Dart frogs would definitely be a good candidate :) Mourning geckos, small day gecko species, anoles, grass lizards, those would also all do well.
