The 30XH is the towering cousin of the perennial favorite 20H gallon tank. With a 12" x 24" base and 24" of height, it stands above the rest. The beautifully expansive front plate provides exceptional viewing area in a small footprint tank. It goes perfectly with a 12x24 glass top (#32412), a 24" full hood (#42024) or any of our 24" strip lights and 12"x24" cabinets.
