I have a few still tiny snails in my 75 gallon tank that is just beginning to cycle. I think they're apple snails, but I'm not 100% sure. Will they die during the cycle? Or will they survive? Also, how to take care of apple snails? Do I need to feed them? So far, I haven't fed them with anything and yet they're getting bigger every day. I can see their tiny mouths (through a magnifying glass) cleaning the glass and plants! I really like them! I hope they're not the bad type of snails for a planted tank.
