Greg,

I am a PADI member...I have snorkeled with Mantas before but never with Whale Sharks, It is on my Life to do list for sure. As for the flower gardens...120 miles at 10 knots or so...8 hour boat ride...they should start a Helo diving tour! lol

I just could not believe my eyes when I saw the whale sharks in a aquarium...How would you keep those guys fed? I mean there are multiple whale sharks and several mantas which are plankton/krill eaters, in that tank or should I say CHUNK of the ocean. Being that Okinawa is an Island, I bet they bring in freash filtered ocean water that has plankton in it.
