I recently added in some new plants to my tank and I ended up introducing camallanus worms. I have levamisole but I couldn’t find any instructions on how to mix it with the food ( don’t have enough treatment to treat all the tanks without using food, plus don’t want to hurt any delicate plants) so I’m going to get some fenbendazole. I know there are some meds that camallanus worms are resistant to. Is fenbendazole one of them? Also has anyone had success using it?
