TheRock,
I'm not crazzy about eradicating bristle worm and their apperance
doesn't bother me, but I want to get the "boa" out of my aquarium.
I can't say that I have an explosion of population, but I can can see
some worms going about their business.
I'm not feeding my tank at all (at least not in last 5-6 months), so
cutting back on feeding will not fix it either.

Thanks
Yuriy
