Well, as much as I hate to admit it, there was a period where my 55 gallon tank was.....neglected. Now a few of my fish have chunks missing from their caudal fins. My Severum is by far the worst off. My Festivum only has one spot of damage, and my Rainbow cichlid had quite a bit of damage too but it has mostly healed. When I first saw this i immediately thought of Fin Rot, but then noticed that none of my Pim Pictus had any fin damage whatsoever. Is there anything characteristic about fin rot (e.g ragged edges, other symptoms) or would it appear the same way as nipping? I also have a Calvus in the tank, but it is much smaller than any other inhabitant and is very timid. The water conditions tested out normal.
