I had a couple pond and trumpet snails tag along on plants when I started my tank. Thought nothing of them, actually enjoyed watching them. Pretty soon 2, turned into 5 or 6 and 2 weeks later I had 20 or more snails.
Many say they keep their aquariums clean...in my case not true. They pooped like crazy, making my sand bottom look terrible, even with constant vacuuming.
