I have 3 fish in my tank right now a red-eye tetra, 1 platy (I did have 2), and a small clown loach. The loach is nipping at my Platy's tail and it looks horrible. What should I do? Its a 10 gallon tank. I've had it a few months and its cycled and everything. I was planning on getting 2 angels, 2 dwarf gouramis, and a painted glass fish also. I'm just worried about that loach thats messing with the platy. Someone HELP! Thanks.
