Help! Whats on my Clown!

[romsoccer12]

their is a big bubble on his fin, looks like a blister, and he has been acting wierd and not eating a lot lateley, i havent added anything to my tank for agood 2-3months and the params are good, nitrates just a tad high, nothing to worry about. can anyone help me out? should i QT him and put copper in? im just kinda clueless on what this can be. no other problems with the fish in the tank or corals. 29gal biocube with chromis and YWG, the clown has a BTA wich host each other, nitrate like 5 and ammonia nitrite0, SG 1.024 and temp is like 78

if i am not mistaken, you should not QT a clown with copper. i think garlic is what you are supposed to use with clowns. i could be wrong, but i could have sworn i read that

Its hard to tell without a pic. I doubt copper would be useful. (although you can use copper with clowns) I would think either parasite or bacterial infection.

i dont have a good camera, honestly it looks like a human blister on his fin, like when they get their eyes all puffy but its on his left fin. i guess ill wait it out?

I would put the clown in a hospital tank.I would treat with Kordons Rid Ich + it has ,malachite green, and formalin. Just remember to do a 25% water change daily....

Rid ich won't do anything its not ich. Its not Brook either so Formalin won't help. If I was to guess I'd treat with Furan II.

hmm.. My best guess is bacterial infection. Furan II. It likely would clear on its own though seeing as its on a fin.
