Fishes near the walkway

Here are some of the fishes caught under my camera at the stream just next to the walkway (the philosopher walk ay Kyoto). The water at the stream really looks crystal clear. I wonder how they manage to upkeep the entire area so clean and even the fishes enjoy their swim.

Have added a close-up on the fishes, actually there are two more fishes swiming on the aquatic plants, i painted them almost the same color as the water itself. Hope you are able to notice them.
