I've been interested in active saltwater sharks like the blacktip reef shark for example and was wondering which is most suitable for a tank/pool, right now price isn't a problem but I don't have space for a tank/pool that's several 1000 gallons but later down the line I will. Right now i'm just curious which of these three sharks are most suitable, a blacktip reef shark, leopard shark and bonnethead shark, I'm wondering which requires the smallest tank/pool, which is the "easiest" to care for and which one overall does best in captivity. I'm asking these because I've seen a lot discreprencies with information on these sharks, thanks for feedback.
