Leather coral just closed ....never opened.... shriveled and died!

I had a Weeping Willow Leather for about 2 months. One day it just closed and never reopened.... eventually just shriveled and died. I still have it but pretty sure it's a goner. I have other leathers, many other corals ....all thriving ... The only change was I added a refugium that dropped my nitrates down under 2 from around 40. No fish in this tank. Two cleaner shrimp that breed and release larva every 10-12 days. Lots of copepods and other live foods. Phosphate also very low. Temp 78F ...pH 8.0-8.1. Everything looks great. Just this leather went from looking very healthy to a total disaster. I understand that this happens unexplainably sometimes...just thought I'd reach out to see if anyone else had similar experience.

You running carbon? Could have been chemical warfare between another leather coral you have. just a guess though.

I run carbon intermittently. I moved the leather to a hospital tank. No improvement so far
