I.D. this worm!!!

[dhalderman]

I've seen this called a bobbit, bristle or eunice worm. This video I have included is not mine, but it is def the same as i have in my tank to a tee. Should I be worried about it? I never thought so but just wanna know if anybody knows for sure. I've spied him eating algae off the rocks, he is very strong, and can now recognize the bite marks on the rock so i know where he's been. But never seen evidence of destruction from him. Heard a lot of different stuff about these worms, what do you guys think?

I had a 4" bobbit in my tank, saw it tucking into a dead trochus one morning, not entirely sure it killed it as I also had a couple of polyclads which killed a few snails but decided not to take the risk. I tried trapping but eventually had to take the rock out to get rid. There is a pipe trap I used you can find plans for online but if the worm is only small you will struggle and it takes a lot of patience. Standard bottle traps don't work as they never fully leave the rocks and are insanely quick and sensitive to movement and light.
