Swimming with turtles

I had never imagined that we would be able to see the turtles so up close. We spotted one in the waters by D'Lagoon but it was like Speedy Gonzales and whizzed away, but we spotted lots more in the waters by the bigger island. The turtles were beautiful and a lot stronger than they look, we would swim with one when we spotted it and wait for it to come up to the surface for air. I discovered the most amazing thing, the turtles were always followed by two long fish who lives under the shells, I think you should just be able to make out a dark shape underneath the turtle in the picture. Thats the fish. Wherever the turtle go, the fish would follow, and the only thing I can think of to explain this is that the fish helps to keep the turtle's shell clean. I absolutely loved this experience, we were so lucky to find them.
