So i noticed this weird tenticle pop out of one of my rocks. Kinda looks like a bristke worm but its huge. This is the best video I could get.

Can you please post some photos under white light?

I can try but he only comes out when I feed so I cant really get good photos.

Probably harmless and feeding on leftover food and detritus. Look up "brittle stars" and see if this matches... My micro brittles extend their arms out from rocks when I feed...

Its definately too thick of a tenticle if its a Brittle Star. I have a couple in another tank.

Agreed that pics under white light would be helpful here.

That said, I'd say to look up Peanut Worms (Sipuncula) and see if that's a match (it looks to me like it might be in the video, but it is hard to tell for sure under the blue light).
