DD , the curviceps are on their own now [ sep tank ], everyone else gets along fine . If I had just 1 curvi it would be fine in my tank .
Aggression between my badis , nannacara and apistos minimal , that's why I switched to them from larger fish
And yes I think they have enough room ,though raising fry is not what I'm after ATM , and can prove hard to do in this setup , no fish are in danger .
