I'm pretty sure its a large female...
Its pretty active compared to dwarf frogs..... Once somebody sits on the cough it usually comes out begging for food =D.
As long as the fish is over 3" and doesn't attack the frog its fine. I kept odessa barbs with it no prob.
she ate my dwarf gourami
.... keep in mind fish aint so quick at night. you be surprised how fast they can lunge once a fish swims by. When the frog was younger it tried to eat anything that moved... even my large bichir lol. Its calmed down a lot since its grown... completely ignores my red tailed shark even during feeding.
Not a good idea to keep it with fish in small tank (10-20gal)..... they can get harassed by the frog especially during feeding time. Most people keep ACF's in small tanks and this is way its generally recommended not to keep them with fish.
