I also saw gray reef sharks on Lighthouse Reef. One of the best dives ever.I understand that large sea life is a component of good dives. And I'm not singling you out here, rather just mentioning some possible places to consider.
Last year I dove San Salvador, Bahamas. Out of the 18 dives there, I did not see a shark only on the last dive, (and it ticked me off), though someone else did.
In 2018, we were at Lighthouse Reef, Belize, (Huracan Lodge), and there were 3-5 sharks on EVERY dive. In fact at both places, it actually became annoying because I couldn't focus on much else while they were around. I know, POOR ME, right?! But when you are trying to focus on macro and these guys want to swim within arms reach of you, you pay attention!
BTW, the tarpon are still on The Hooker.
As for turtles on Bonaire there is a grass flat on the south end of Lac Bay where they feed, rest, etc. and seeing 30 there is not really all that hard.
Tarpon are on the Hooker, in the deep water at the end of the Salt Pier and on other sites like hanging around the anchored sail boats at Something Special.
