Holy cow, Kitkat. I'm really sorry to hear about your concinnus. Even though your ordinoides appear fine, I suppose you're already treating them with flagyl as well. Snakes have a good tolerance to it, and it's very effective against amoeba and protozoa. Prazaquantil treats tapeworms, and it's available from that Pet Revival source you gave to me. I also had great results with Fenbendazole to treat for nematodes (round worms). Tapeworms have an indirect life cycle, so they wouldn't/shouldn't build up to deadly levels in a captive-born snake, but nematodes have a direct life cycle. The Fenbendazole can be bought at almost any feed store that sells horse supplies. It's sold under the brand name Panacur. If you get it and want to use it, I'll help you with the proper doseage. Best wishes and condolences,
Rick
