I just accidentally dipped the same hand from my qt in my display tank. The qt tank has a powderblue tang that doesn't seem to have any external or mabye any internal parasites. But I'm still not to sure. My hand was kind of dry before I dipped it in. How high is the risk of a parasite getting into my dt. Because I really don't want to lose all the fish I have in my tank because of a stupid mistake.?
