Hard to tell without a white picture.. almost looks like Dino’s from what I can see on the branch if that’s what you’re talking about?

To me it looks like the flesh is still there it looks like it is just browned out from lack of light.

Actually I can’t edit my post but I see it now. Ur parameters look good. How often do you do water changes?

If it was rtn/stn it would be bone white, so its not that. I don't see much movement on the polyps so it might be low flow? How long have you had it?

I see skin on the left and not on the right. IDK.

Could be from many things. When I see this happening and not stopping, I just snip that off and remove from system. Usually heals up.

I've been doing 10% every week. Initially also think that part lack of light but it's standing at center of the tank with full coverage.

It has ton of flow at center of the tank, maybe the video too short to see.
I got it when it was a very small frag, it's been a year and still thriving. Recently I see it losts skin but can't get what's wrong with my tank

I Really love this frag, don't want to lose it.
