Patch on clownfish

[DavidA]

What is the brownish patch on the top of the orange clownfish? He has had it for about 2 days and the patch seems slightly larger. He is less enthusiastic about food but still eating. Otherwise behaving normally without

flashing. Of note, a biota mandarin recently died after developing a patch of hypopigmentation and not eating. No fish or coral added for many months.

Looks like clownfish bruising and as a precaution, add ruby rally pro which addresses many clownfish issues and is safe for inverts and coral

That does look like CBD, I have a thread about it here:

Clownfish bruising/lesion?

All, Over the past two years or so, I've come across dozens of cases on the fish disease forum here of an issue with clownfish that we have not been able to identify. I've never seen it on any clownfish I've had myself, but the issue seems most common on designer clowns, which I don't work...
