FB's are fun, do you know how large your tank will be? I would keep frogs with frogs. When I found mine at petsmart they had frogs in with crabs. Well, frogs can hop but crabs can pinch. I would not keep them together. I have a 10 gal aquarium with a submersible heater (water 76 degrees), driftwood, treehouse, pebbles for land with round big flat lid with eco earth fiber in it, plus large smooth rocks, live and fake plants, terra cotta clay pot for hiding. I have them in some humidity. I read that frogs are ok without a heater then later found better source that said they like it warm and somewhat humid. By looking at them they look like a variety that prefers warmth. I feed mine several kinds of worms and crickets. I would like 2 more FB's and a total of 4. Oh, be sure you have a screened lid. Another tip: have a tall tank so its less likely they can escape. Mine don't even try! They must like their home, especially without crabs. Hope this helps.
