torch

My torch coral has suddenly began to recede. Parameters spot on. Water changed 10% last week. No other additions or changes. All other corals looking beautiful. Carbon changed out with water change. Any ideas?

Anything bothering or nipping at it?? You may not see something just pay close attention.

Anything's possible, although I've never seen anything pick before. I'll continue to watch for this. Moved it to the other side of the tank this am. It has been in the same place for a year.A frogspawn was within 6 inches. Both have grown since I bought them. Maybe chemical?
