need some advice on my clowns....

okay, so i started out with 2 ocellaris clowns… all was well.
added 2 black percs later, percs establish dominance… all was well.
one of my ocellaris somehow took an overflow/sump/filter sock ride and didn’t make it.
i bought a beautiful ORA snowflake ocellaris that was about the same size as my other ocellaris, but he seems to have become the unloved stepchild of the group. he is constantly chased away by one of the black percs and as of today, i’ve even noticed a slight degradation of his color. the poor guy is constantly hiding, but also deals out his own fair share of aggression.
any ideas for what might be done? stick it out? stick him in the fuge? find another home for him?

Read up on sexing clown fish. Some species of clownfish when they become a dominate female can’t switch back. If you bought a single ocellaris that was by itself it could be female and two females will bunt heads. Perhaps that is the case.

How bad is the aggression?
