I have four neon tetras in a 10 gal. tank. I noticed early on that one of the fish was a little nippy to the others. As the fish got larger this seemed to stop. However, the top fin of one of the fish took a pretty hard hit. Today when I looked at the fin, the top fin is almost completely gone. Everyone appears healthy other than the missing fin. I have not witnessed any aggressive behavior recently. Do you think this could be fin rot? If so, how do I treat it? Will the fin grow back?
