Problem Male Taiwan Reef

Hi,

I have several haps and peacocks in a 125 gallon tank that I've had for about one year. I bought all the fish as juveniles and they've all grown up together. Lately I've been having aggression issues with one male Taiwan Reef. He's bullied all the fish to one corner of the tank and he's injured one female to the point were she lost one of her eyes. I've tried rearranging the tank twice. I also tried changing the temperature from 80 to 78 degrees. I also tried moving him to a separate tank (timeout) so the other fish can recover. But as soon as I reintroduced him back he immediately started fighting and chasing the subordinate male.

Other than re-homing him are they're any other suggestions that I can try?

Thanks,
D

Remove the females, males aren't as aggressive when they can't spawn. Lower the temp, they don't really need much above 72 if its just a display tank.
