Hello...hoping someone can point me in the right direction or might even know off hand if you can get snails for a cold water tank. My parents have a 29 gallon heated tank and a 5 gallon with a gold fish in it and was wanting to get a couple snails for the 5 gallon as they have them in the heated tank. Does anyone know off hand if they will survive in an unheated tank. Thank you for your time. Have a great day!
