Also, if you have frozen blood worms, try soaking them in garlic juice. Fish go nuts over garlic. I get the minced garlic in a jar at the grocery store and just use some of that juice, put it in a pill cup or small vessel, soak the worms, and then drop them in.
The live worms may do the trick, but if not, try the garlic.
