Yes its not just in middle school. I added 2 royal blue finned wrasses today from Jays. Nice and healthy and eating but my other fish are not cooperating. I dont need any more new fish suicides. Any advice.
+1 to flame angel. Another idea is to re arrange your rock work, and it resets the territory a bit so fish aint so possessive of "my spot"
Also, feed more so they dont fear starvation from competition. food is a nice distraction.
I wouldnt worry unless they start posting it on FB. Like other have said take the bully out if you can and throw him in the sump. Also rearranging rock work can also help.
