Worm Identification

[nrbelk]

I found these white worms crawling around a dead fish I found in my filter sock. I checked the other socks to see if there are similar worms and didn't see any. Are these just young bristle worms that haven't developed their color yet or something more nefarious?

Are they spiky?

definitely just bristleworms, I have 500 of them in my tank

One of them was spiky when it curved the righ way, hency why I thought bristle worms. But the other two or three I saw I could never be sure if I could see the spike tufts on the side.

The color threw me off too since I've never seen an all white bristle worm.
