Scot why not try a clown loach. They do get big, but do an awesome job of ridding your tank of snails. I would only use a snail killer as a last resort because basically tou are poisening your water. Snail acide may kill ALL of your inverts including amano shrimp and such. Marcus Http://www.Aquatic-store.com co2, plants, lighting, filters, uv and more
