Does anyone know how to get rid of snails? I don't buy plants from the pet shop, but I buy the bulbs at walmart. I've never had a problem with the bulbs having snails, but one day I notice snails in the tank and I hadn't put in any plants or anything in almost a year. Now I have an infestation that I can't get rid of and they are eating my plants! Is there something I can put in the water or a fish I can get that doesn't eat guppies, but snails?
