Picture is pretty blurry. Is it a hard tube attached to the frag?

Looks like two tentacles come out and shrink when light is flashed

it shrinks when i cycle the light on the magnifying glass. Looks like two tentacles come out. Couldn’t post vid

I'm thinking vermetid snail. Does it retreat into a hard tube, that maybe is coiled up, and is stuck in place? If so that's a vermetid. They are a pest. Their slime nets irritate corals, they clog up plumbing, and their tubes become razor sharp knives that will cut you and your fish.

Video's working for me.

Hard to tell, but I'd say probably some sort of detritus-snagging worm. Spionid, maybe. If it's not irritating the zoas, nothing to worry about.
