Many states don't allow for the sale of native fish and some you can't own them at all. However most let you own and sell/buy them so it's sad that they aren't as popular as they should be in the hobby. People are to set on "natives aren't hardy and need coldwater" or "native fish are boring". I feel the opposite, I keep mainly natives plus a good bit of tropical catfish and I feel that there's many ignorant people out there because they're not even willing to try natives and feel that tropicals are the only thing that can be kept. Now just predict what would all us American hobbyists do if the aquarium heater wasn't invented, oh yes, we'd more that likely be almost all native keepers and be happy being them. Just my two cents.
