ID on this mass of tentacles

[Srosco02]

At first I thought it was aptasia, but I'm now certain it is not, it is nothing like the aiptasia that is also in the tank. They are small hairlike tendrils that are able to wave around on their own when the pumps are off and have no visible polyp body structure. Please help ID this monstrosity.

Maybe spaghetti worms. Add some sauce and meatballs.

+1 looks like a spaghetti worm to me too. Unless it's a Kraken, then I'll be jealous.

Thank you! That seems to be likely what it is, though I'll keep my fingers crossed for a baby kraken!

I am rather jelly. If you do not want him, seal him up in a bag and ship him to me.

Keeping the little beast, he popped up after the last time I went to the coast and brought back some water and sand. Perhaps if I target feed him he will multiply!

I have a beautiful large green one that I call The Grinch.

Yep spaghetti worm.
Normally you won't see anything but a bunch of tentacles spreading out from a central point in the sandbed, but in yourimage you can see the tentacles all bunched up against its body. These tentacles are not meant to catch live prey: the spaghetti worm feeds on detritus, leftover bits of all sorts of small dead organisms.
The spaghetti worm’s burrowing nature protects it from natural predators. A startled spaghetti worm will quickly withdraw into its burrow, retreating its tentacles and remaining invisible for a while.

Indeed they seem to be pretty awesome critters! I think from the distribution of the tendrils that I may have more than one!
