Bristleworms

[geopod]

Man, I used to have the same problem before I moved from Nova Scotia to Edmonton.I used to have hundreds of them in my tank.Anytime feed was there they were out like crazy.Now that I moved I think most died off cause now I only see maybe 1 or 2 once in awhile.But there is no cause for concern as like evryone says here they are beneficial for the tank.
