I have been very interested in a shark tank or pool for my home for a long time but I am unsure which shark is most suitable, I am aware there are smaller bottom dwelling sharks but I'm more interested in sharks like the blacktip reef shark for example. Expenses and space isn't a problem and I'm in no rush so I have plenty of time to further educate myself on the needs of these creatures, the three sharks I've been interested in are the blacktip reef shark, leopard shark and bonnethead shark, which of these would require the "smallest" tank/pool and which would be the "easiest" to care for? I'm ready to make the commitment of caring for one of these sharks and was just not sure which one would be best.
