Something eating soft coral?

[Terence Trent]

Has anyone seen this before? It looks as if something is eating only my pineapple soft coral but haven't seen anything yet munching on it.

It's hard to tell by the picture. Sometimes soft coral can get an infection and start melting away. It could be that. If so, cut the infected part out, it will grow back.
