That's why they are the best pictures

Most of the guys in ANGFA that take fish pics takes hundreds or even thousands before they get the one really great shot of males showing off together or a male and female displaying or actually breeding. That's one of the advantages of using a digital camera, you can take thousands of pictures and check them on the computer. Delete any you don't like and keep the rest. Recharge the camera batteries and take more. Eventually you start getting the odd picture of males displaying or a fish yawning, or something unusual and that goes into the keep file. It's just a matter of practice, practice, practice, and sometimes you get lucky and happen to have the camera pointed at the tank when the fish do something really cool.
