We did snorkelling on an organised tour while we were there and I had such a good time. The guide was explaining what we may see while snorkelling and told us not to worry about the silver finned fish, we didn’t think much of this until a Turtle started swimming up from the bottom – it was enormous, so what the heck were those silver finned fish that were swimming next to the Turtles! Glad I didn’t think about that while I was swimming around in the open ocean hehehehe
