Some sort of worm found in sand?


Reefing newb
Hey guys,

Ive been doing a major cleaning of my tank, when i was cleaning out the sand i found this weird worm type thing inside the sand. Does anyone have any idea what this is? Should also note that this had been soaking overnight in a bleach and water solution, so this might not be how it originally looked. Picture to follow:

That is a peanut worm. They are really gross and creepy looking, but they are harmless and reef safe. They are quite common to find as hitch hikers in rock and sand.
