Fireworm?

[Alexis56]

I've been seeing these worms in my nano tank lately. I'd like to know if they are a fireworm or a good bristle worm because I do have a lot of healthy corals as of right now. Thanks!

Bristle worm

Look more like a fire worm from the coloration be careful not to touch they have a powerful sting!

Fireworm and bristleworms are the same thing. It is a general term given to any polychaete worm with sharp setae resembling bristles. The only true "fireworm" that is harmful is Hermodice carunculata, which is rarely seen in the hobby. Those are beneficial "bristleworms".
