Just as I was entering the water at Honokeana Cove to snorkel with the turtles, about a week ago, when I looked down and saw this fish. At first I thought it was an octopus by the way it seemed to be slithering over the rocks away from where I was standing in about 3 ft. of water. I lifted my head to tell my wife there was an octopus in the water. When I put my head back in the water, I realized it was not an octopus but some kind of strange barbed fish. I have checked some books on reef fish and it may be some kind of Lionfish, but I'm not really sure. It appeared to be about 16 inches. I am hoping someone can give me a positive ID on it.
