I would suggest for a common nurse shark about a 5,500 to 7,000 gallon minimum. 10,000 is probably an excellent size for them. Since it is only 5 foot in lengh right now a 3,500 would probably do nicely. I feed them shrimp, octopus, and fish. He should get 10-12 feet in the proper enviornment. You can't exactly ship a 5 foot nurse shark very easily. At least without risking it's life. Cost depends on a lot of things: how far you are from original home, the cost of the truck to move the animal, and the labor involved with helping you to get it setup in your home.
