Worms in tank, infestation or beneficial?

[free]

Don't know the name of them, but they live mostly in substrate, pink, look like centipeeds.
They are growing to be quite large...

I have seen it debated whether they are a good or bad thing.
What do you guys think?:frustrat:

Sounds like Bristleworms to me. They do a good job of keeping things clean. Some people swear against them, but I have a few and have not had any issues

sounds exactly like bristleworms, they are very beneficial detriavores. hang on to them, if you decide you hate them get a 6line wrasse, they will keep populations in check

Good. They are scavengers and will take care of uneaten food.

they probably came in on your live rock; generally speaking, they are beneficial.
