Pocillopora concerns

[Adam1103]

Ey every one! Ive had this pocillopora for about a year and a half now and has been doing great until a few days ago. It had a few white areas start to develop on it a few days ago. Almost like something had eaten the polyps off of it. Now it seems like more and more is missing. I'll post a few pictures.

Looks like rapid tissue necrosis to me.
