Hello all, it looks like one of my clowns has fin rot. His tail fin looks more lik3 it was caught in an impeller to me, though it is virtually impossible for it to happen. I was on vacation all last week so im assuming stress is a likely cause. It is quite active and eating, but there is also a very thin white film on it that i can hardly notice. not sure what to treat the lil dude with but he's going in QT in a couple hours. Here's a pic, please post what you think i may be able to treat the water with to help the lil dude out. I have prazi pro and cupramine. Not sure if either of those are going to be of any benifit. THX !!!
