Snorkeling at Dusk

At 18:30, Wing Lung Rd., low tide. Water cooled down a bit, visibility still good, but daylight fading. Tons of crabs out, very active. Large swarms of little silver fry, shooting around sardine-like. Unfortunately, no octopus. This would have been octopus paradise; they have to somewhere. I must go at night, and bring a torch.
