I agree this is a special fish not suited to the casual aquarist and I don't remember ever seeing them in the "trade" in my over 50 years in the hobby. They are however an aquacultured species and I see no reason why experienced, well-informed fishkeepers can not help add to the body of knowledge of this fascinating fish.
grow up to 5feet, and can be 50 years old. a fish in my opiniun that should not be in the aquarium trade
