I had tried countless time to take a good pic of my pet arowana using a Nikon D40. Before the shot,i cleaned the tank,off all the light outside the tank and just by using the 2 huge tank light above the tank. The problem is i just cant get a good pic of my fish. I had off the flash trying to get the natural colour of the fish,but its turn out blurish as the fish is moving at all time. I really need some professional help here in order for me to get a good shot of my fish.:cry:
