Just saw this guy on the side of my tank. Any ideas as to what it is?

Nudibranch. They look like what they eat. Some consume zoas and montipora, so are generally considered a pest.

^+1^.
Did you just get coral or LR?
I had a bunch that looked like "green star polyps".
Or do you mean little curved worm next to nudi?

That doesn't look like the zoanthid eater, nor does it look like the monti eater.

I think he meant that black worm next to the nudi.
