EMERGENCY what is this?

So i put them in a new tank,

I used biospira

@Humblefish had concerns with beneficial bacteria degrading CP. Bright light is another alleged concern although I don’t know how much I believe that one.

Try a freshwater dip, see if any small sesame seed looking things come off. Use a dark bucket so you can see.

You should do anyway for velvet. I’m guessing your cp was removed or not potent enough (not pure enough). I’d use 80 instead of 60 since we cannot accurately measure it anymore.

I'm just going to use copper and yes i saw something like little sesame seeds coming off my coral beauty after a freshwater dip.

The little sesame seed things are flukes coming off of the fish's skin.
