Anyone have any idea what is killing this fish? Got this blue damsel about 5 days ago. 2 days in he started to look like he had white patches on top of head that looked almost like he was losing scales there. He wouldn’t eat so I moved him to quarantine tank because I thought he might have been bullied by my clowns. The white patches have turned into this brownish red color and it looks like skin is sloughing off. Still won’t eat and is breathing rapidly. I tried melafix for 2 days and today put Ichx in tank per LFS advice. If anything he looks worse now
