So today my platinum senegal bichir went nuts and attacked my platysilurus mucosus, taking his barbels off and shredding his tail. Now I have a cup I use to deal with my cats so they don't get hurt from nets but in the case I had to use a net to remove as he was getting mauled and could not get him in the cup., I cut the fish out of the net but a piece is stuck on his dorsal spine. Any tips to remove this without harming him? It is not really affecting him at all he is swimming around fine in his temp home.
