Months ago I noticed a cory missing its tail fin all the way to the base. 8O It has a difficult time swimming and kind of wiggles to get to its food. I decided it must have been somehow injured. The rest of the fish seemed okay so I left it at that. Yesterday, I took a closer look at my other fish. My 7 glow light tetras seem fine. My 3 Corydoras aeneus also seem fine. But my 2 other Corydoras elegans appear to have diminished tail fins although not as bad as the one with the missing fin. They spend all day together inside a cave ornament so they have very close contact.
Does this sound like fin rot? Or could it be something else? Do fins ever grow back? What can I do? Help!
