Read up about Flatworm Exit and be careful.

Wash your hands thoroughly after touching zoas.

Wash your hands thoroughly after touching zoas.

Wash your hands thoroughly after handling ANY coral!
(Not because you're worried about any particular toxin, but because of all the bacteria in the tank )

Buy a lipfish, it ate all my flatworms better then any drug you pour into the tank i would say
