I think it's ick

[mdlc805]

Hwllo I purchased a small blue tang about a quarter size from my lfs 3 days ago. I didn't quarantine him and am seeing white spots on him I'm thinking it's ick. Do I need to take all my fish out and copper treat all fish or just him?

All fish need treatment! Separate and dose copper is your best option.

Do you know how long my system has to be without fish?

To be 100% 76 days fishless, 60 days kills most ich strains but I'd go more just to be safe.

I've done 6 weeks fishless and put my fish back in without a problem. I've read again and again 72 days but I did a lot of research and kept reading 6 weeks tried it and it worked. Your call 6 weeks or 10 weeks
