Naso tang mark on side seems to be alittle flakey but acting normal and eatting normal. I am treating frozen food with general cure and focus was wonder what u think it may be? I purchased him 4 days ago and he was in copper treatment for a week when I got him
Appears to be post-injury but do keep an eye on it. One great thing about saltwater fish is their ability to heal quickly but can also develop into a bacterial issue
Mine has had much more significant gashes and cuts. Mine likes to tail whip things he doesn't like and tends to get into tang aggression when he is bored or hungry. He has always healed well but I do try to ensure I'm putting selcon on the nori when I see any visible injuries.
