Feeling sick to my stomach !!!

[miyags]

I put my copperbanded butterfly fish and a clown fish back in my tank 13 days ago. After being fishless for 73 days. Now I see spots on the tail and one side fin of butterfly fish and saw the clown chafing. So I guess 72 days is not enough. Now I read its 90 days. Wish I read that 73 days ago. Like I said feeling pretty sick right now.

Did you QT them first? They could have already had something.

No the fish were taken out of DT for cupramine treatment. Then were put back in DT after 73 days and I think they might be getting reinfected.

How long did you treat them with Cupramine?
