Yea. I got some of my nerites and my AES from them as well. My horned nerites and AES are eating algae non-stop. I still throw in some algae wafer and shrimp pellets every now and then. Are you going to keep the baby snails or you would want to get rid of them? In a couple of months(if the baby apple snails hatched), they'll be big enough for you to pick them up. You can also put a blanched zucchini or cucumber to attract snails and just pull them out with the vegetable. Good luck with your tank.
