I agree that sharks and rays need the right type of person to care properly for them. Like Jack said, these are dangerous animals.
As for being cruel, you would be surprised at how many miles a yellow tang can travel in a day. or how much territory an eel has in the wild. There are times when i think i just might have to revert to small fish when my large ones die. Getting rid of them is out of the question now that i am responsible for them. It is one of the reasons i am upgrading this year.
