Not a problem with fish because the worms drown quickly, but it's a serious problem with reptiles & birds who hold the worms in a crop or gizzard before digesting them. Mealworms must have their heads crushed or removed before feeding to reptiles or birds.Sean_Buckley said:Is it true that if you don't chop off their heads that they can chew their way through the stomach lining of the fish?
