Any suggestions for possible tankmates for a Chubby Frog?

My twin brother finally succumbed to my addiction for Frogs and Reptiles. But, he wants to make a decent ecosystem with multiple species, but, he's set on a Chubby Frog. Any suggested tankmates or will these Frogs eat anything in front of them?

He was considering Anoles but further research makes me think Crested Geckos would make a terrific match.
