Bristle worms are tuff

[.AcroKiller.]

I have a few bristle worms that were on a few rocks that I used on my quarentine tank and this things are still alive with the .50 of copper on the tank I figure it would have killed them but not the case

Take a piece of panty hose and tie a chunk of shrimp in it. Put this in the tank over night. The bristle worms will go after the shrimp and get stuck on the panty hose. Remove the panty hose wrapped shrimp with bristle worms attached in the morning. Have seen this work very well.

Oh I was not trying to get rid of them I was stating they are taking the copper treatment
