A few tips for taking photos-- never aim staight-on at the glass or the flash will bounce back at you. Take pix on an angle, and pre-focus if possible. It also helps to not have anything beside the tank that can be reflected on the glass. Dimming the lights around the outside of the tank may help the camera to focus on what's inside it. If the camera has anti-shake, use it. If you are closer than 18 inches, use the close-up setting. Take a bunch of pix and choose the best ones, rather than trying for the best shot each time. Aim at the place where the fish will probably go and hold the camera steady, don't try to 'follow' the fish. Bribery is ok, feed them and snap away. Have fun!
