I'll take a pic later....
Just bought a 45 gallon for my new crib.... I went freshwater... Make sure you supplement your basic tap water with some sort of conditioner or stress coat everytime you add it to tank... Fish... I only have 9 right now... Pink Guormis, Gold Guormis, a shark-shaped guy, and a tiger striped guormi... Keep nasty goldfish out your tank... get good filteration system... and of course... water temperature.. Be patient.. Let the fish create the BIOLOGY of the tank... Don't overfeed... Most mofos want to see the fish "dance", so they feed them constantly... Bad move... Buy algae eaters after about a month (you ain't gon have no algae before then)...Keeping your light OFF when you ain't there will also keep your algae growth down... That Doctors Fosters and Smith site is a good one.... Buy natural stuff (rocks, etc.) for your tank.. Plastic decorations from Petco are expensive as hell
