I recently got 2 new true percs and the bigger one is beating the hell out of the smaller one. They are not paired yet I think. I put them in at the same time, so there would be no fights over territory. I've seen the smaller of the two do the shake, etc when the bigger one comes by. Then the bigger one does the same. I guess from what I've been reading, they are playing with each other. But the smaller one is really beat up... bitten on the top fins, etc. I have it in a little holding thing inside my tank so they bigger of the two can not get to it. Is this normal for the clown to be beated and so on to a point where it is just floating close to the top? It eats and swims perfectly fine.
