Hi Nano Guy,
I had several bristol worms in my 15 gallon and tried the panty hose trick but it didn't work for me. The one thing that did work was sucking them up with a turkey baster right after feeding time. However, I had so many that I decided to start over from scratch and got rid of hundreds of them by doing so! I did hear that having a few is not a bad thing but they do become a nuisance. The reason I had so many was because I over fed my seahorse but I now feed her with the turkey baster and I find there is a lot less food going into the tank. The turkey baster is a must have!!
Good Luck,
Shanon
