Nailed it!! Bristle worm. Good scavengers they vast vast majority of reefers leave them. Try not to touch them with bare hands there is a reason they're called bristle worms

That's quite a collection of bristleworms you've got there. Depending on your tank size, there might be an overpopulation problem. I'm just guessing, though, based on them swarming when you feed the tank.

I think of it like this, for every 1 that you see you probably have 5 that you can't see. When I see them out at night I use a pair of tweezers and pull them out gently so they don't break and split. They are great at consuming uneaten food and detritus, but as mentioned they can over populate and become an eyesore. So kept in check I think they are fine, when you start to see them on every rock I'd start with some manual removal.

You could put some shrimp or something in nylons and theyd get stuck pull nylons iut and more you're set.

Thanks. I will leave them for now. Because that the place I use to feed the fishs. That why they crowded under that rock, as long as it not harm to my corals.

I personally feel they self regulate pretty well, just means that there's that much excess food for them. Remove them and might have more food decaying.

Agreed, those are definitely bristleworms, freaked me out the first time too, but I think they're harmless.
