I am thinking I am the only one that sees snails as an indicator in a tank of the tanks health. Snails will be the first let you know if something is wrong, to many snails means you are feeding to much, snails trying to escape get your tests kits out and check for ammonia first and then nitrates and nitrites. I have several planted tanks and know that the snails will let me know if something is wrong way before the fish start showing signs of stress or disease. I have found that the snails don't eat healthy plants either, only dead or dieing plants.
Please don't get a fish to clean up the snail problem unless your tank is large enough.
