Keeping fish is a minor passion of mine.  It's not easy as some people think, but harder than keeping up a tank is taking pictures of one.  After about a zillion shots and 1/2 a zillion adjustments, this is the best as I got.  Back to the drawing board for sure.

This is the summer evening light shining through the Mamossa tree in my backyard. f-stop of about 3.2 and a long shutter speed because there wasn't much light.  Hardest part was keeping the camera still.  It was a major issue for both these "shoots," so I know I need to invest in a tripod.
