Bristleworm or something different?

[the_chef_pierre]

I keep finding all sorts of different worms in my tank. This one looks like a bristleworm near the front but then the rest of its body is dark and blackish coloured rather than pink. Is it still a bristleworm or something different? Gonna attempt to get all these worms out eventually

Yup, regular bristleworm

Thanks crab. By the way, did you see my other worm post? The other guy is about 6 inches long and a bit flatter. Still not fully sure if it's a bristle or fire worm. Any opinion? Its definitely thicker and flatter
