• If you are setting up a photo tank, make sure to get it setup and ready at least a few hours in advance. Clean the glass inside and out.
• If pictures are to be taken from an established tank, you must make sure to remove any algae buildup from the inside. It is best to do this every couple of days. You never know when you are going to get that chance for a great shot.
• As you know already, lighting is everything. I try not to use the flash, though The flash tends to distort appearances, in my opinion. I use a portable fluorescent light usually placed at the top front of the tank. I also use an incandescent standing light to help out, placed at 45 degrees to glass to reduce bounce.
• If using a bare tank you should place some sort of background behind the tank. At times I use cut out pieces of cardboard painted a different color on each side -- I have pieces painted blue/black, yellow/green.
• Place some live plants in the tank towards the rear.
• Loosely tape a mirror to the side of the tank if possible. Pull it off if male gets too freaked. :-) I have one now on an extension arm.
• If you must use flash, angle the camera at around 45 degrees to the glass to help prevent flash bounce.
• I usually only take pictures of the fish when they are up front close to the glass. Placing a cup or other floating plants close to the front of the tank helps quite a bit
• If using a digital camera, set the camera to the highest resolution you can. Fine mode at 640 X 480 (I believe) on the FD71, 1024 x 768 on my [Sony] Mavica Fd81
• If you are using an SLR camera, consider getting an extension tube for the lens. Macro lenses for SLRs can be quite expensive, while tubes are only a few dollars. My links page has some URLs to resources for photography.
• Consider buying a close-up lens if the zoom of your digital camera is less than 8x. It cost me around $40, I believe. Using a close-up lens usually requires you to use manual focus. Practice makes perfect. :-)
• If attempting to get spawning pictures make sure the nest is built towards the front or a side that is accessible.
• Reds and yellows (non-iridescent [fish colors]) photograph better with a flash. Blues and opaques are quite a challenge, sometimes producing too much glare.
• Take as many pictures as you can! If you get a great framed betta just keep shooting as many pictures as soon you can until he moves! Usually you will get a few great poses. I literally have *thousands* of shots. The ones you think are good sometimes are not. Others you think are crap turn out great. My favorite photos sometimes come by just grabbing the camera and shooting at a fish.
• Get a good photo editing software package to remove any flash remnants from the photo. I use mainly Image Composer from Microsoft, but many others will do just fine.
• Bring your favorite beverage along with you. It could be a while! I personally like Sam Adams :-)
  
  
• Bottom line: Lighting, patience, lighting, lighting, patience and lighting.
