If you ship them, you'll get a wide range of buyers. But you have to learn state and country laws, they've becoming increasingly banned in more and more places. But otherwise, there's a strong (cheap) market for them... they're regularly sold on aquabid, ebay, aquariacentral and here.
ill ship them the same way they got shipped to me....they are about 4 months old but still smallish because i kept them in a 10g for so long. email me. ampthefrogguy@gmail.com
Step 1 Buy a 200g tank

Step 3 buy a Fahaka or one of many saltwater choices (I lke Dog Faced and Stars and Stripes).
Step 4 put a Cray in the tank
