Two tenticals in live rock

[Bahreef]

Hi guys I found this in my aquarium wonder if anyone knows what it is.

It has a long thin body with two tenticals on the end and lives in the live rock.

Thanks

Pic very fuzzy to get clear view but two tentacles suggest spinoid worm and tentacles are used to capture food
Place a dab of gel superglue from the dollar store over it and it will starve

Seems to be some sort of worm with the biggest tentacles I've ever seen. The video is much clearer than the picture.

Do they move on their own or only because of the flow?

Ribbon worm (Nemertea)? These are predatory worms and are not reef safe.

I considered these, but couldn’t find any with noticeable tentacles. That first picture you found looks way closer than any of the ones I was able to.

Definitely not spionid.

OMG, and yet another horror of the deep! This is going to give me nightmares!

Dang. Looks like the first picture might have actually shown a harmless green spoon worm.
