What is this!?

Found this in my tank last night, and I am lucky it is still there this morning. Anyone know what on earth this is?

It resembles a big clump of worms, with sweeper tentacles stretching over 1.5 inches.

Looks like a spaghetti worm. They are harmeless filter feeders.

My guess is aiptasia.

My guess is aiptasia.

It’s definitely not an aiptasia.

Looks like a spaghetti worm. They are harmeless filter feeders.

So I should just leave it be?

It has been under my mushrooms before, which sort of irritated them. So I don’t want it messes with the coral.

Leave it alone, picks up left over foods.
