How can snails just appear in a tank of pond water that didn't have snails before?

Wade Thomas; Cincinnati, OH

Sounds like maybe you started an aquarium and ended up with some surprise guests, huh? But no need to worry--it's not magic.

Pond snails lay their eggs in jellylike clumps on underwater plants. I'll bet you put in some pond plants that already had eggs on them.

It's good to have a few snails in your tank. They help keep it clean by eating algae. And before you know it, you might just find a whole new batch of snails!
