Nitrate alone won’t cause tissue recession like this. See mine below. My nitrates routinely run that high with bo issues. You have something either picking at it causing it stress or you had the same problem I had where you have some kind of parasite inside the coral skeleton.
It looks to me like it’s just stressed out. If it doesn’t have feeders out stop trying to feed it. Your stressing it out worse. Feeders look like the 3rd and 4th picture I’ve attached.
you don’t need to move it if you don’t want to. My green ones are literally 2” from the waters surface in my biocube and getting hammered from my pump and they’re doing better than they ever have.
The only fish you have that I would even worry about messing with it would be your wrasse. I had a green corris and he could be a turd sometimes. But that doesn’t look like the issue.
Candy canes can regenerate tissue loss. My huge colony straight up died down to bare skeleton and came back to turn into this. Leave it alone and let it get used to your tank and get healthy
I didn't spot feed the coral this coral. Only squirted some food at the top of the tank. Last time I try spot feeding was the first of this month and that was the first and last time I spot fed. And nothing has picked at the coral, so it maybe the same problem u had. What did u do to get rid of the parasite?
