In your reply post,
Please also list its actual dimensions.

Start with myself.
My biggest aquarium is a Seaclear acrylic 40 gallon tank. Manufacturer rated it at 40 gallon, but its true size is 36" (long) x 15" (wide) x 16" (high) = 37 gallon. With the space above water level, and the room for the substrate, the actual water inside is probably around 30 gallon.
