I personally remove them from my tank. Do you seem to have a problem with them? As in way too many in the tank? If so a good way to remove a lot is to take a piece of shrimp and put it into the
Foot section of panty hose and tie the top. Put this in your tank after the lights go out. The bristle worms will try to get the shrimp and their bristles will get stuck in the panty hose. In the morning remove the panty hose along with the bristle worms.
I see more then I would like , there not in my 75 there in my biocube 29 so maybe I just notice them more in a smaller tank. And thanks for the tip I'll have to log that in my book. I log everything just one of my habits
Yeah, they serve a similar purpose to earthworms. Don't panic if you see them on your corals - they will not eat live coral tissue, just dead and/decaying bits and detritus.
