Looks like a bristle worm to me

Thank you. It seems to be just feeding on the algae but i wasn’t sure what it was or if it was bad or not.

Here's a pic of just a few I have taken out of one of my tanks. They are a good part of CUC although they are ugly. Just don't touch them with bare hands. The bristles will get into your skin like fiberglass.
