Dwarf Blue Crayfish (Cambarellus Shufeldtii)

They really nice. I would like to get some, but have been unable to find them for sale. If you have a source for them I would appreciate knowing it. Your pictures are really great.
 
They are not Cambarellus Shufeldtii, they are Cambarellus diminitus and soft water turns them blue and hard water turns them brown
