How do you get rid of Nematodes? Nothing seems to kill them. I've tried conventional parasite meds, but that didn't seem to phase them. Is there anything out there that will get rid of them but not kill the fish at the same time?
Update: I treated with Levamisole last night, and the worms were gone in 12 hours. I used a small dosage (1ppm). The Nematodes are tough buggers, but they were no match for the Levamisole. It's great stuff!
