I just discovered I bought some fish with a camallanus worm infestation. Can these worms be passed onto apple snails? Turbo hasn't been looking so hot lately and I'm wondering if thats why.

Shes about a year and a half so I suppose it could be old age, but I am not sure. Also is fenbendazole (dewormer) harmful to snails? I read mixed reviews over whether or not it was. Thanks again and have a good day!
