I've been Quarantining my clowns for about 2-3 weeks now, and i bought it from someone on craigslist. They're med sized pair of clowns and they're been in my 10 gallon QT for 2-3 weeks like i said before. I've added cupramine, then i realized that their skin is white and a bit bumpy; ich to my guess. They had no sign up until now. they were healthy in the other guys' tank and they're probably in there for about 6-7 months based on their size. What's wrong with my QT? all parameters are right.
