During a recent visit to a Baltimore area aquarium store I asked about the availability of ramshorn snails, and was told they are not for sale in Maryland due to being considered a pest. Is this true? Also if not, does anyone within say an hour or so drive from Baltimore have any Ramshorns available? Color isn't much of an issue-my last surviving ramshorn from a batch I got about four years ago is the brown color, but any available color is fine with me. Many thanks in advance.
