i tihnk u could saftly put 4-5 in a 10 gallon with no other fish maby a small catfish included but 4 is safe and 5 is pushing it but its up to u they may get stressed unless u have 'many' hiding places or a well planted tank if ur going to house 5+.....
Well now I have 3 of them in the tank. I think I will just keep these ones. Got a question though, when I go to feed them and after putting food in they dont seem to eat, why?
