Hi, I have a convict that has white like cotton spots (large) on the base of his fin. I want to treat him, but he and the misses have babies right now. Is it safe to treat the tank or should I take him out to treat him. I thought maybe I could dip him and then put him back in. But, not sure what he would do after being away from the babies and then back with them. He might eat them or something or the misses might not reconize him. Anybody, have some thoughts on what I can do. Thanks
