I'm hopefully planning on never letting ick in my dt by qting everything wet for 6 weeks. I haven't incorporated any prophylactic treatments with these first two clowns. If they are healthy and eating well and not stressed, won't the ick just lie "dormat" with the fish fighting it off or will there definitely be signs of ick or other diseases throughout the QT period even if they are adjusting well to their new surroundings?
