I couldn't lower the shutter any further, it's still blurry But um you can see his colours! He doesn't have as much red wash as it looks like in the second pic, but the first is about accurate. He's a veiltail and flaring in these pics.
A suggestion for fish photography, i find the pics turn out much better if u darken the room and place a light directly above the fish or tank. Iv got possibly the worst camera on earth and iv turned out a few decent pics this way.
It also helps if you put your camera on top of something, so your not holding it. I have to do this cause my hands tend to be shaky and I can almost never get a clear picture because of it. Stacking books up works fine.
