ok so as the title states, I have a yellow coris (also known as canary) wrasse, he has been in quarantine for just over 3 weeks. he looks extra clean but I occasionally see him rubbing on the little rock in there, and a couple other things. the first time I saw him do it, I did a 30 minute cuprimine dip, but he still does it some times. I have seen other canary wrasses do this as well, but wanted to get the green light from the pros here just to be safe. I do have 2 juvi clowns in the dt and just want to look out for themthem. Tia, Tony
