Actually, the three meds are probably the most commonly given (Flagyl, fenbendazole, and metronidazole), and all are very effective. Maybe ask about all three at once, or different combinations. I was asking about Flagyl & metronidazole because protists/amoeba and roundworms are commonly contracted by feeding fish, which is often a large part of the diet of garter snake diets.
