Hoping for some feedback on spaghetti worms

[Michael]

I was doing some research on how I can make my sand bottom of my 60gallon aquarium better. If you've seen my previous posts, you know it is clumping together, and getting black hair algae on it.
I was given some information that spaghetti worms would be a good addition to it as well as cerith snails. The snails I know about, but am not familiar with spaghetti worms.

Can anybody say whether spaghetti worms would help my situation, or would cerith snails be fine. (1 blennie, 1 brittle star, 1 damsel, 2 peppermint shrimp, 20lbs live rock, blue legged hermits, turbo snails)

(wonder how the spaghetti snail got its name )

Thanks

Michael
