I loathe them as well. I try to net out some periodically to feed to the Botia striata tank and they disappear in that tank, but the Botia sidthimunki don't tend to keep them under control. I wish I'd never added them to any of my tanks. I've heard a rumor that cold temperatures (below 40F) will eradicate them.
