As was previously posted, a betta vase is OK if all the "ifs" are met... - IF the water is kept clean - IF the fish can get to the surface - IF the fish is fed properly Bettas are a special case though. From what I know of the dwarf frogs (I have one now) I would not put it in such a small container. They do like to move around a lot... a lot more than bettas, that's for sure. I'd say that a gallon is the absolute minimum for them and 5g is much better. (That's my tank at work.)
