White/Swollen lips on Clownfish

[jlt716]

Hello all... I have two false percula clownfish, that I purchased separately (about two months ago), not mated...in the hopes they would mate. One of the percs is larger/slightly older and the other is smaller/younger. The older/larger perc had definitely shown dominance and it seemed that although she was very dominant to the other fish, there didn't seem to be any issues. A month ago I purchased a rose bubble tip anemone and just last week the smaller/younger perc hosted the anemone. I was very excited about this, but it seems since the smaller perc has hosted the anemone the larger, more dominant perc has become extremely aggressive toward the perc hosting the anemone. He is consistently being cornered into the anemone whenever he tries to leave it's area, and is being bullier non-stop. I am not seeing signs that the smaller perc's lips are turning white and are swollen. Any advice would be much appreciated.
