I've received my 29 gallon about a few months ago. My cousin set it up for me, and it's been doing perfectly fine. Well, about a month ago, I noticed I had a snail. I emailed her about this, and she said they never bought any snails, neither have I. Since then, another has appeared. They're very tiny, and seem pretty harmless. But last night, 2 more smaller ones appeared. If they're bad to have, I'll get rid of them, I was just wondering how on earth snails came into my tank.
I also do not have any live plants.
