Fujifilm FinePix S700
The best way to take pictures is to use the macro/super-macro setting. It's a little flower buttong on cameras. That will make it easier to focus on something closer, which greatly reduces blurriness and makes picture overall better quality.
Also play around with the lighting. I find my pictures are best when I turn off the room lights and just have the tank lights on with no flash.
A good tip is to hold the button half way down, let the camera focus, then click the button all the way to take the picture.
:) Good luck.
