I've been told african clawed frogs need isolated tanks (or get a 20-30 gallon with two clawed frogs around the same size). So my question is, would it be feasible to have a clawed frog and betta fish in a 20 gallon tank, with no one else in the tank? My own betta fish is very timid (he is currently in a 20 gallon with 3 corry fish, if the corry get too close to him, he swims the other way) and I've thought about getting another clawed frog (my last one passed because she ate something she shouldn't have eaten), but if I did get another clawed frog, she/he would be strictly in the 10 gallon on their own.
Long story short:
is a clawed frog and betta fish possible to be housed in the same tank, if the tank is 15 gallons+? My last clawed frog tended to hang around at the bottom of the tank only and my current betta is more of a mid-tank dweller. I know clawed frogs can get pretty big too.
