a: from my own experience, the apple snails are not difficult when it comes to food . feed them fish-food (food for pond fish, it comes in a big box, consist of big pellets and is inexpensive), cucumber and lettuce. apple snails consume a lot of aquatic plants and algae and can be very useful in eliminating...
