Not to be a spoil sport.......but.....
Have you ever tried to collect fish on a reef?
I live on a small island in the Pasific, surrounded by small reefs, it is not an easy task....
But ......Just getting one tank to an island like mine to be in the hobby, is quite the logistical and expensive undertaking, I can't imagine acquiring enough equipment to maintain proper holding facilities for fish, and consistent power to keep them alive. (Power on these islands is inconsistent at the very best) Shipping costs (to ship a 1 ounce letter to the states within 48 house is around $50)
not to mention the local traditions and politics (this is a big one).
Unless you've got enough disposable income to overcome all the above.

Getting my single 180 gal to the island where I live (hiring a truck, and people on the mainland, a boat to cross the Pacific, and people on the island to get it to my house) cost the same as buying the tank (and tank cost here, is between double and triple stateside cost).

Above I added a 50 gal since, after about a year.
By the way, there are no LFSs on islands like this, where you might get pumps, fish food, meds, etc so any of that usually involves a trip to a major city on the mainland for supplies, and cartage costs.
It is an interesting adventure, I wouldn't trade for anything, of course I'm not trying to make it a business.
