You do need to feed your snails. Many snails die from starvation all the time. Especially apple snails. I feed mine slices of peeled potato and apple. They really enjoy that. You can also give them zucchini. Pretty much any peeled veggies are good. I would imagine they would probably like carrot too. I know mine also like to eat peeled peas.fishcatch22 said:well, you don't really need to feed them, but if you insist, just about anything organic they will eat no problem!
