Bristol Worms are they ok ?

[daniella3d]

That's my only cleanup crew. I don't have any crab, or shrimp, or anything else beside some snails and bristle worms. I do kill them to keep the population in control because they encrust in my zoanthid frags and beleive it or not, sometime I can pull 30 bristle worms from a single small zoa colony on a small rock, and some of them are quite big.

I use peroxyde 3% at 1/3 concentration with tank water and I watch them pour out of the rock and float and die. Best way to clean a zoa colony from them. I don't think they eat the zoanthids but a lot of them are upseting the zoanthids and I have seen a few times some zoanthids with a lot of bristles in them, so that can't be good.

So I tolerate them to a certain degree but from time to time I clean up my frag of them.
