Snails have a high bioload.... I think the min. tank rec. for them is 5 gallon... but I would say 10 gals just to be safe.
For smaller tanks, consider shrimp, either ghost or cherry, they are extremelly entertaining, live 1-3 years, have almost 0 bioload, and help clean the tank up, not to mention ghost shrimp are 33 cents at walmart, lol
