My Onyxclowns are paired up, although one is not bigger than the other so I don't think one has turned into the female. Anywho, I bought a True Perc from Reef69 and now my Onyxs are beating the True Perc up. If I get a Blk/Wht will that keep the fighting down, by add more members to the pecking order or is my best bet to find a good home for the True Perc?
