Help with Clown

[EJS107]

I lost my male Clown overnight, I saw no signs of parasites. When I cranked up the white on my lights it looks like my female clown has a white coating. All other fish seem fine.

Any help appreciated.

I got all of my fish out and into a hospital tank. Treating with a copper based med. Hopefully everyone pulls through.
