I'm sorry,

I made a mistake. I assumed that since I saw sharks in both california and florida pet stores that AZ would have no problem. Apparently, they do for the stupidest reason in the world.

Call these pet stores to find out.

"I don't know anything about "crazy California" laws but unless something has changed here in Arizona it is illegal to own one in an aquarium. Get this, the reason why, they don't want them being released into any of the rivers or lakes!! ^^& ^^&
Its not like an alligator, I mean a shark has 0% percent chance of living in any river or lake here.
And before anyone pipes up, yes I know some bull sharks can survive in fresh water. I've heard stories of people catching them as far inland as St. Louis.

All sharks need ROOM… to move, grow, dilute their wastes, allow for gaseous diffusion of gasses for respiration… Not hundreds, but several hundred to thousands of gallons in the case of Triakis… Tanks of less than ten feet in length, five in diameter are equivalent to you or I being confined (permanently) to a closet… behaviorally, physiologically and psychologically prohibitive. The road to heck is paved with good intentions or so it's said, but thinking that you'll "get a bigger system" when your shark/s grow larger is worse than wishful thinking… it's outright cruel. Let me repeat this point in a different way to emphasize my intent: IF you don't have a tank at least ten by five feet DON'T try keeping even juveniles of this species. On the plus size cost, maintenance and operation wise, the height of the system is of less functional importance… so yes, you can keep such sharks in round, rectangular "swimming pools" of a depth of two, three feet.

Filtration, circulation, aeration are critical elements of the care of sharks, the Leopard inclusive. For animals that "store" a good deal of nitrogenous waste in their bloodstream (the rationale often offered: to establish osmotic barrier to salt in their environment), sharks are intolerant of accumulation of same in their captive systems. NO detectable ammonia, nitrite OR nitrate is the goal you want to prepare for and achieve. Simple wet-dry filtration, ammonia towers, fluidized beds… will NOT do… chemical and/or biological scrubbers, extensive live sumps (refugiums), deep sand beds (DSBs)… and the like… of SIZE, capacity are required (unless you have access to clean seawater…) to maintain these fishes. Circulation and aeration need to be brisk, the water kept in motion for exercise, filtration purposes, and dissolved oxygen near saturation (about or greater than 7 ppm).
