Thanks!

I cranked the aperture to 32 in Av mode. I probably didn't need it that small, just where the dial settled. I wanted to force a small aperture to increase the field of depth so more of the shot was in focus. The camera processor then set auto ISO at 3200 (that's why the shot looks faded a bit instead of rich) and the shutter speed in most shots settled somewhere around 0.4 to 1.4 seconds. With such a long shutter speed (Tv), it was important to use a tripod and use either a timer or a remote as I would shake the whole thing if I pressed the trigger on the camera directly. Also all power heads in the tank were unplugged. I'm thinking that I didn't need to crank the aperture so small as that forced a high ISO and longer shutter speed than necessary. I've had some luck before using Tv mode and forcing a long shutter around 1 second and let the camera calculate the rest.
