Thanks We already had awesome dives with Tiger Sharks at Fuvahmulah.In response to the above, yes it is "possible" to see tigers, bulls and blacktips...tigers are more and more regular in shallow water recently.
But I wouldn't plan a trip here for that. The sightings are generally brief and definitely not "guaranteed" like the threshers pretty much are at the moment.
But the chance of oceanic black tip and tigers (even if brief) along with seeing the threshers and everything else again makes me consider our return … after Dauin and Tubbataha and South Leyte….
