What's wrong with my cup coral?

Looks like something did a little grazing there. Just my opinion, don't know for sure.

Thanks for the reply. Yeah, I'm not sure what it is. My wife said she noticed the discoloration last night at lights out. I haven't noticed any of the fish (hippo, powder blue tang, flame angel, pseudochromis, occelaris') nipping at any of the corals but I could be wrong. It looks more like the tissue is starting to slough off.

I had a pagoga cup that suddenly got a few pock marks. Don't know what caused it, but now that I think about back it could've been when I started using kalk and had my Alk spike on me. Good news is that it eventually re-grew the tissue.

Oh I hope it regrows. I'll have to recheck my params.

Are there any corals close by that could have stung it?

It almost looks like coralline algae growing on it.

I thought about that. I do have a small torch around 6 inches towards the bottom right corner. Also a blasto above it. If anything the blasto has a more direct line to the injured part. I wasn't sure those sent out stingers like a torch does.

Well, this is what it looks like tonight. The slough area is getting larger. And I don't know what those little dots are.

I would iodine dip it. It may or may not help but if it's a bacterial infection of some sort the iodine can kill the bacteria. It certainly won't hurt it.
