Good guy or bad guy?

Should I kill it or let it live?? Looks like and moves like an earth worm.

I would remove any worms out of my tank.

How big is it? It looks kind of like the baby bristle worm pictured in the link below. (Polychaete-Dorvilleidae)

I agree cloak.

Ditto on bristle worm.. Good part of cuc. Just don't touch with bare hands

Do not touch with your hand. Take them out and wash it. During the night every bristle worm will come out and try to catchthem one by one or buy a catchworm

What's wrong with bristle worms? Mine come out even when the lights are on and clean the sand and rocks.

Bristle worms used to be considered pests and were removed at first site. We've come to understand them as a part of our clean up crew. You can leave it be.

This actually isn't a bristleworm in that sense. Like Cloak said, it's a Dorvilleidae, which are herbivores. They don't share much in the way of behaviour of "regular" bristleworms. These will not stick bristles in your hand. The size you see is it.

Sorry, my comment was on bristle worms in response to Tori, not on the ID

It wasn't just your comments, but.... ummmm.... all of them.

Ah! Just realized they were two different species. I have to start looking at the scientific names more

I'm pretty sure the ones I have are all common bristle worms.
