Diver swarmed by fish in Hawaii

— -- Kawika Singson was diving off the coast of Hawaii on Wednesday when he got "schooled" by some fish.

At first, a puffer fish seemed curious about his underwater camera.

Then a huge group of fish swarmed Singson and the camera. There were so many fish that they nearly blocked all sunlight streaming through the water.

The fish eventually swam off, leaving him on the hook for sharing his experience.
