Was cleaning up my old tank and I found many of these in the sand. Is it a worm? Anyone knows whats this?

Hmm.. Does it cause any harm? Found so many when cleaning up the old tank.. Heh.. Anyway all flushed down the drain cause I didn't want to throw them into the new tank..

Any bristle along the side? If yes, bristle worm. Peanut worm is harmless. Bristle worm, debatable. I normally remove any I see.

Agreed with bro Iskay , that's likely a peanut worm .

The peanut worm has a proboscis that resembles an elephants trunk, as well as a mouth that boasts an impressive array of tentacles. This bottom burrower feeds on organic materials found in mud and sand, and when done feasting it can turn the proboscis inside out to retract it inside its body. Peanut worms are often tiny but can reach 1.5 feet (0.5 meters) in length.
