What in the Cthulhu is this. Looks like there's a body of some sort In the crevis but with a mass of spaghetti tentacles out searching. Any ideas what this nightmare is.

Either a spaghetti worm or a hair worm - it's harmless/beneficial (so a keeper):

Looks like either a hair worm (Cirratulidae) or a spaghetti worm (Terebellide) to me - if the tentacles all come out from a single point, it’s a spaghetti worm; if they come out from basically all over the body it’s a hair worm.
