Is this guy bad?? What is it??

[lsawchuk]

Hey everyone. Pls help. What is this and is it harmful andddddd how do I get rid of it?? It's a stringy black creature. It's on the rock and you can see the strings touch the sand bed..

That looks like a spaghetti worm - and a pretty good-sized one!

He's stretching out those tentacles to snag bits of uneaten food and other detritus, which he'll reel in and consume. Not much for elegance or decor, spaghetti worms are pretty good to have around as part of your janitorial crew!

Looks like you're starting to have bubble algae too ( 2nd pic). I would remove it asap. Don't want that to spread.
