Aquarium Dimensions

Below are the standard rectangular fish tanks made by Aqueon (formerly All Glass Aquariums) and Marineland (formerly Perfecto). I do not have a preference for either brand over the other, in my experience they both make high quality, reliable aquariums.

Not all of the tanks listed below are available from both Aqueon and Marineland. Most come in multiple color options and most of the larger ones are available pre-drilled with built-in overflows (some overflows are built in to the corner, others are on the back). Some tanks have center braces built in to the top frame, others do not. If this is a concern just ask and I will check to see what the options are for you.

This list includes the basic/standard rectangular tanks. This list does not include bow fronts, hexagons, cubes, columns, Marineland Deep Dimension tanks, etc. I prefer the standard tanks below because you get more volume for your money. Per gallon the special shapes cost a lot more. If you are interested in any of the other tank shapes just ask me.

For reef tanks I suggest a tank at least 18″ wide (front to back). This gives you enough space to setup a stable rock pile as well as allow enough width inside the stand for a 12″ wide sump. This would also apply to tanks for African cichlids where you will also have a lot of rock work.
