You should google them. They self clone, are all female, are non-cannibalistic (a rare thing in crayfish), and don't eat other fish! If anyone wants one I am selling as soon as they clone themselves. My prices will be 6.00$ for a young one, 10.00$ for a female that has never had eggs, and 15.00$ for females that have had eggs (every time they get eggs they have more babies), and 35.00$ for a female carrying eggs. The female's carrying eggs are expensive because you are basically buying 1 adult+ 400-1400 babies every time.
