I am aware you can keep a shark from growing its full size, like feeding it less often, and having it grow to fit a certain size tank
That is just a myth....
If you are speaking of Carcharhinus limbatus you would need a huge tank. I believe the IGFA recognizes the world record of 220 lbs. They are also very active sharks that need huge amounts of swimming space. IMO, keeping one in all but the largest professional aquarium tank (maybe even in one of these) is inhumane. If you want to build a tank for large sharks, look into leopards or smoothounds. Bo
