Ok, so my 14-15inch Silver Aro semi recently got a few slight nicks in his top fin. This has happened a few times in the past and they usually heal up like brand new and go away. This time around his nips do not seem to be healing up properly. I had a 4inch pick cichlid in there which I assumed was the culprit and moved him out of the tank about a month ago. Although the nips do not look super bad, Im curious as to why they haven't repaired themselves by now. Any suggesstions?
