The pond at Marie Selby Garden has a happy population of Koi. They are very tame as they are fed by visitors each day. The bottom picture shows their enthusiasm whenever people come to the edge and look over.
I used a polarizer lens to remove the reflections on the water. One sees through the water as though it isn't there. When the bottom is clear of litter, it appears that the fish are flying. It takes a lot of pictures to get a few of these. But then, it is wonderful to watch the Koi swimming the pool, coming around for another look at me and then back around to the front where some more visitors have arrived.
