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:
