Help my salfin fish

[Robert Staie]

I have had good success with using a cleaner shrimp for parasites and Vitamins such as Selcon to improve the fishes own immune system. This will not help with severe Bacterial infection. I would recommend moving fish to quarantine tank and treating with medicine their instead of main tank if inverts and coral are present. I have a reef so treating fish in main tank is very tricky.
