Hello, I have a baby porqupine puffer and he ate alot of raw shrimp the second day I had him(3 nights ago). The next morning his fins and head had white spots all over him. I then changed the tank over to hyposalinity over 6 hours per LFS(he said that was aggressive but all other fish were fine). Now he has white film over his eyes and little dangly type growths hanging off his skin. He is trying to hang on. Spends most of his time laying on the tank floor breathing but every few hours shoots up to swim for a bit. His fins are covered and his skin is filmy as well as his eyes. I have water at 1.008/9, melafix, copper and formalin in tank(all minor amnts). All other fish are doing well(2 clowns, snowflake eel, hawk fish, 6 line, goby). Please help this little one survive. Suggestions? Do you know what this is??? He has been swimming right now, more than the last 2 days. Looks terrible tho. THANK YOU!!
