mysterious tentacles in sand

[Lilbitreefer]

So I was feeding my tank some frozen food. Looking down at the sand I saw these really long tentacles coming from the sand. I noticed it was going after a rather large chunk of meat. Upon further inspection I started to a bunch of them through out the sand bed. They all have at least two long tentacles with 2-3 other shorter ones. At first I thought they were brittle stars but I don't think this is the case. Any thoughts people. Thanks

Might be spaghetti worms; which are good. They will populate based on the amount of food available. They have long translucent string-like tentacles that stench across the sandbed looking for food.
