Well before I get into my real post let me start off by saying amazing eels. Now onto this Shark issue. You can read, post, and ask questions as much as you like. But until you actually own a Shark or Ray and have that first hand experience you are just stating facts which anyone who could read or write will know. However inorder to get to the stage where you are capable of housing Sharks and Rays ethically you need to go through all of those stages so I am happy lots of people are doing that. As for Bigmans Shark, from what I can see he had 2 Nurses, 1 Leopard, and 1-2 misc. Rays. The Rays would have been fine in his set up, the Nurses would have been fine in his setup as well for 1-2 years, and the Leopard seeing the small size of it would have been fine for up to about 2.5 years. He said the longest he had one of the Sharks was 3 years so really he wasn't doing anything in an un-ethical sense. Some may argue he shouldn't have purchased those Sharks knowing they would outgrow his system, however atleast he was smart enough to get rid of the Sharks when he knew they had out grown his tank. On a side note, that Leopard does look a little small, but the whole Lacey Act ordeal in my mind is just stupid and out played. As long as a knowledgable experienced Aquarist wants to own a Leopard under 36" go for it. Its when the Leopard pups are being sold to LFS to people with 90 gallon tanks the whole process becomes an issue.
