It srtarted a few days ago. He has a white film that started to grow all over him. This morning I noticed his tail looks like it's been chewed off as well. I've been all over the internet and this is the best link I found. Brooklynella I have the clown in with my tang in the QT tank. I'm aware copper does not help cure clowns or other fish of this parasite. Being it's Sunday I'm having a hard time fining somewhere open that carry's Formalin 3. Can this clown be in with my Tang in my QT tank and also do I need to set up a seperate QT tank for when I do get the Formalin 3. From what I read this parasite makes quick work on the host so I hope he makes it. It's hard to grab good pics, but here are a couple of the clown from yesterday. He's much worse today. I'm starting to think my new 75gal tank is jinxed. I want my 55 back!
