Is this a bristle or fireworm?

What is this? And should I remove it/be worried about the tank? Any help or info would be appreciated! If closer pics are needed I can use microscope if that helps. Thank you!

Just a regular bristleworm. Nothing to worry about!

Ok great should I remove it? I’ve read they’re actually kinda good for your tank but can get out of control and infest, so I want to stop that before it happens!

I like them. Seem to be a beneficial part of clean up crew. I do not minds seeing like 5 every foot of tank at night. Mine have never gotten out of control, cuz I feed an amount that fish eat within a minute

Then again, I have seen some very disgusting amount. Like you drop a peice of food in and hundreds come up from under the rocks

They aren’t bad for tanks. I like to keep them around, they only help the cuc and my pistol shrimp eats them.
Many people do find them disgusting though.

Wonder if they aerate the sand like earthworms do
