Sipunculid but tenticles too long?

[Elliott Comans]

Saw this critter in the filth of the sump. It seems to have ling feeder tenticles but also a swirling mass of tenticles (mouth?) . If the video works you can see it clearly when I zoom in. Couldn't see a body.
Any help would be appreciated, I'm super interred in what this could be. First thought a species of sipunculids but tenticles seem too long. I know cucumbers can gave long feeders but they look the slime not defined tenticles like these

Looks like the feeders of a vermetid snail

Dont they send out more of a stringy tentacle. Or are the feeders that are visible normally in the tube

Vermetid- generally one or two. Spinoid , one and spaghetti worm- many
