alien in my tank

[jreefer113]

theres this wierd thing living in one of my rocks. it extends long thin tentacles from inside the rock. i cant get a picture becuase i doubt it would even show up. it makes piles of sand on and around the rock. what could it be?

Spaghetti worm maybe?

ive never seen it..............just the tentacles sticking out and the sand piled up

That pic is in its raw form. It does use sand as a form of camouflage.
