doesnt look good. quickly remove it when you still can see this.

seems like nudi or some sort of slug? i dunno.. but definitely doesnt look friendly.

Looks like a compressed bristle worm? Or a sea cucumher

It's moving slowly in my tank, not going into the rocks.. Will it be harmful to fishes or corals?

It looks so cool imo, but it doesn't look safe :/ Maybe you could put a glass cup over it until you can get an id? Then it can't wreak havoc in your tank

looks like trouble. I got sting by bristle worm and had to pluck each needle out of my fingers one by one. Fingers got water bubbles for a week and feels funny for a month! This does not look like Bristle but remove it or place in sump until you are sure. Dont make a mistake like me to let the small bristle go during the cycling period.

That's a fireworm! Not a bristleworm! Bristleworms are fairly harmless and won't sting you
