Thanks good to know both the fish and camera as that is what I have too.
What sort of setting do you use? Adjustments?
All photos are raw off the camera, with zero adjustments. I am thinking of getting a photoshop lite type program as I lost a lot of good pictures to little things that could probably be corrected very quickly and easily. When I shoot fish I use the little running man setting meant for motion on auto fire setting so I can snap off a bunch of pics really quickly. I also find this setting helps when shooting under the LEDs so you don't get soo much light hitting the sensor. I have been thinking about getting a macro lens as well, but still making up my mind on that (tamron 90mm which gets great reviews or go up to the 100mm nikor products which get amazing reviews and about a 300-400 price differential).
