Angel Fish sensitive to Fenbendazole?

Camallanus worms have been found in one of my fish. (Red worms sticking out of anus, and bristle-like). After a lot of research I just ordered Fenbendazole. I tried Prazi-Pro, but didn't have any luck. I have one Angel Fish in this tank, and I've heard they are sensitive to meds, especially in the water. I also heard they need just half a dose. I'm afraid to mix it up, feed the medicated bloodworms to them just to have her get sick or worse, die on me. What should I do? My meds should be here tomorrow. I don't want to put her into another tank because she might infect them, as I've read that you should assume all fish in the tank are already infected. So I'd just be spreading it. THANK YOU! Any feedback would be great.
