White cloudy patches on my butterfly fish

[htjunkie]

My butterfly fish seems to have developed some cloudy white patches on one side of his body, he's the newest addition to the tank about 4 days ago. He was okay when I got him.

I'm trying to take some pics but he doesn't seem to swim the right side that I can take pic of. I'm fairly new to SW setup so I'm hoping I can treat it properly.

My tank currently has a pair of clown, one basslet, some cleanup crews.

I noticed the same thing on a Royal Gramma Monday...

By Thrusday 7 fish were dead.

3 left... It In my case it was Velvet / Brooklynella.

Cooper treats all so i hope for the best.. Spent all night ctaching whats left and putting them in QT.
