Coral eating pest?

[ccejka]

I have had this green coral for about a month and it has been looking good. My tank is located in a retail store and I did come in and feed it on Saturday and everything looked fine then I had on of my employees feed the tank on Sunday.

Come in today and this coral looks like something has been eating it... Then when looking closer I see what looks like some little type of critter down where the rock and coral meet. I tried to get a picture but as you can see it was tough to get it in to focus.

I have been watching for a bit now and haven't really seen any type of movement so maybe I am just crazy.

It looks like a tiny white centipede under there, I am going to be pulling that frag I am guessing is montipora eating nudibranch going to try to suck them off the rock before pulling the plug

Montipora eating nudibranch is my guess
