I've had my fish in qt for 3-1/2 weeks now after my female clown was covered in ich and coral beauty and male clown had 4-5 spots. The cupramine was at .5 for 20 days then I lowered it to around .4 to try to get my coral beauty eating again. The clown looked completely clear within the first week but then I noticed these bumps/spots again. It looks nothing like he did when he went into the qt. I took these pics last thurs and I think some of it has disappeared but can my clown still have ich after this long in treatment?
