I have been using several lighting techniques to highlight the reef subject (fish, coral, invert, etc.) and eliminate the distracting background. Of course, this can be accomplished via photoshopping, but I try to do most of the work in the camera itself instead of manipulating the electronic file picture in post-processing.
Some techniques I have used can be done very easily:
Flash snoot: use a 1/2 cardboard roll from paper towels and tape it to the front of your flash. Cover any other parts of the flash so that no light leaks out except for what is going through the snoot. You may have to aim the snoot at your subject and the snoot will light up a much smaller area.
LED Flashlight: I use an LED flashlight on many occasions, especially at night, to light up my reef subject. The other tank lights are generally out for the night, but there is still a lot of action going on in the tank.
Off Camera flash: This technique is the best for shooting fish if your camera allows for it. Most DSLR's can use an off-camera flash. Mount the flash high on either the right or left side pointing downward towards the subject.
