My friend took this photo at a fish shop today and asked me if I knew what it was. Sorry the photo isn't very good. She said it is a vibrant blue fish with that very weird looking nose. I've never seen one around. Does anyone have a clue what it is?
That is a bird wrasse it is indeed saltwater not fresh and sadly that is a growth of extra skin that can develop on this type of fish and over time will kill them. It seems to be a pretty advanced case of it from that pic.
