I've been out of the house since 8am and checked/fed my fish(had a short photo session) before leaving. I'm finally getting ready to go to bed for the night so I go check on the fish before lights out(they are in my basement) and this is what I find!!! How did this pop up so quickly? I know this fish has been lip locking but I've never seen anything like this before....What is it and how do I treat it? Could it be a secondary infection due to lip locking and getting injured? How did it come on so quickly? Help! I've asked to have the FS ad closed on this fish and the other since I obviously do not want to sell a sick fish..
