Crates are highly specialized for transport of sharks, and for aquariums getting sharks from the Pacific that are on flights, obviously, they need to be crated. They are often accompanied on the flight by an aquarist, or in transport, on specialized tractor trailors, with aquarists. The delivery of sharks for aquaria results in a very high price tag per individual, and rarely are they immediately put on display. I highly suggest you consider a QT system, of at least several thousand gallons, depending on the size shark you intent to import. But it needs to be a totally separate system.
