I'm rocking a 29g planted tank with about 2 1/2inches or so of sand; today I did a water change and unearthed a snail that was almost an inch long.... I have never cleaned algae off the sides of the tank in 2 months and now I think I know why.

Anyone wanna guess how many are actually in my tank? I originally bought 2 plants and my LFS gave me a bunch for free when I returned a koi. From reading they seem to be okay in planted tanks and they don't bother me. I'm going to check the tank late tonight with a flashlight and see how many I find.

Long term do I wanna keep these guys or not though?
