Ok lights just came on and the birdsnest def looks worse. It is not tissue recession...it looks more like the whiter areas have had the tissue scraped and the polyps look mashed. Now on my green/orange formosa it looks like there are some coralites that are sorta bent/mashed and these are a touch white.
All looks like physical damage to me and not recession or die-off.
I'll be watching after lights out tonight but I think my hermits are going to get yanked. I don't even see them grazing the rocks during the day anymore.
