A couple of suggestions from the above information:
A shutter speed of 1/8th of a second is way to slow to freeze movment. Get it up to at least 1/60th. Try changing to shutter priority and see what that does for you. You may have to raise the ISO in order to do this.
Get rid of the red eye reduction feature. This delays the time from the pressing of the shutter and the time the picture is taken.
When using a flash, switch to the manual flash white balance and when not select the shade setting.
One more thing, when taking a picture of a fish that you want to be the main focus of your image, use spot metering rather than pattern metering.
There...That ought to keep you off the streets and out of trouble for a while!
