I found with my pair of WC henkeli that they had good body weight/appetites and I did not feel a need to medicate them. They have done just fine. But if you have a specimen that looks thin, doesn't have a good appetite, or has an obvious parasite load in the stool, I would medicate. I use Panacur once a week for three weeks, and then Flagyl once every 2 weeks for 3 doses. This will knock out the parasites. Dosage for both meds is 100 mg/kg, but do this under vert supervision if possible. It's easy to mess up, especially with the Flagyl. Good luck!
