Okay, I did a search on google and all I found was some stupid dolphin and shark salt and pepper shakers. I am not sure how to make this any clearer...SHARKS ARE NOT APPROPRIATE FOR THE HOME AQUARIUM, ESPECALLY FOR SOMEONE WITH LITTLE TO NO
SALTWATER EXPERIENCE!! Everyone agrees with you in the fact that sharks are awesome creatures and amazing to watch. But there are many, many, many other cool things much better suited for a home aquarium. I see you live in Illinois, I sugest you buy a season pass to the Shed Aquarium and visit sharks there. See if they offer any "behind-the-scenes" tours or classes so you can learn just what it takes to keep these creature in captivity.
