Thanks for the answers, I heard they are found singly or in group of 5 in the wild but I guess my tank is a little too small for them. I'll probably keep one of them, they are beautiful fish. About their diet, do they take pelleted fish food or does it have to be frozen stuff. I know they need to fed 3 times a day too because of their small mouths. Has anyone seen this fish eat commercial food like New life Spectrum, I heard that was a good food that almost any fish will eat.
