What is this worm ?

Hi, the tank is almost 6 months old now. Started with dry rock and was selective buying from coral vendors. Always dipped and double dipped before putting corals in. However this worm came out of nowhere tonight after lights off. You can see it next to the tail of the fire fish that is resting in the crevice. The video hopefully helps. Thanks.

Harmless, common bristle worm. These will multiply over time and are good detritivores. Try not to touch them as the bristles will painfully break off in your skin.

Thanks. Found only one so far. I will balance feeding to make sure that their population doesn’t explode.
