What the heck is this?

I just spotted two of these on my live rock. About 3-4mm long. They seem to move around by extending that rounded "head" end like a hood. I could swear I just saw this one eat a pod off the LR. Pest?

Ghost flatworm.

IIRC, they do eat pods - possibly annoying, but not alarming.

Looks like a flatworm. Maybe acoel? Not necessarily a pest, but can still get to pretty large populations.

Well, I'm not all that concerned about them eating my pods. I have a thriving population and I'm not planning to keep a mandarin or anything like that. I just hope these guys don't wind up reaching plague proportions.
