And yes corals look fine same as always have.Well I’m sure I’ll get crucified for this but no I’ve never QT new fish. Not gonna lie. Hadn’t added any new fish for months till two weeks ago.....a mandarin which seems to be doing great colors bright and out and about grazing on/off live rock all day. The other two fish that survived don’t have ich but aren’t eating like usual. What do I do guys??
