Listen... Matt is right on this one. The seller should know what their selling and care a little bit about where the fish is going. I used to feel that this all fell on the buyer but after dabbling in the business a little and suppling some rarer fish and a couple of small sharks to people, my opinion quickly changed. I also have seen where some of these more common animals are held at the local wholesalers and was shocked by poor conditions and lack care for what happened to the animals. So as someone with the ability to supply sharks, rays and fish I am very particular on what and who I sell too.
