I was buying a couple fish a while back and to my surprise the fish lady also put a snail on there without her knowing I told her and she said it was okay. At first I was a little excited to have a snail in my tank since I never had them before, it was quite small. Couple weeks later I saw more snails I didn't know they could have babies that small (no idea what type of snail it is) I know they are asexual so they don't need a partner. Now I have couple more snails and my dad's telling me they are spreading to quick. I was wondering is having that many snails is a problem I stopped counting at 20. D:
