I have a canon rebel digital SLR and I have taken lots of great pictures with it but I was wondering how you guys get good pictures of your fish against dark backgrounds. I've painted a lot of my fish tank background black but I still can't manage to get a good picture of my fish on a dark background. The only thing I can think to do is bring the light all the way to the front of the tank and kind of angle it outward a little bit. The only other thing I can think of would be to focus on the fish really good. Also.. Glass cleaning tips? I usually just use windex and am really careful not to spray it in my tanks. I know its harmful to my fish so what do you guys use? I'm not about to buy $6 aquarium safe glass cleaner when I can take my time and use $1 off brand windex.

That pleco has a serious fungus problem around it's mouth..... do you want me to take it off your hands
