I got my 2m/1f Super Red Calico BN's from Aquatic Arts, who are Indiana based and often have diff locally bred BN Morphs.
They're good people to deal with and they have quality stock, a lot locally bred. If you live in Indiana they're 100% worth checking out:

(they sell my high quality line of Malaysian Trumpet Snails, so I may be biased)
