I'm not big on the general cure all medicine. I use a different method for internal parasites, worms. I get adult brine shrimp and gutload them with panacur. After about 8 hours of gutloading, I feed the brine shrimp to the frogs. It's not exact in the dosage, but it seems to work great. I feed them the gutloaded shrimp every other day for 3 treatments.
