I have this naso Thang being treated and copper with a green spot in Puffer Fish box fish and blue powdered tang he’s eating but his breathing seems weird like he’s panting almost and he’s staying near the surface I noticed that he had this hole in his side a couple days ago but I thought it was an injury accident but it seems to be getting worse he staying near the surface I’ve been treating with the Mela fix and Prima fix along with copper what should I do
