Aqua One Arc 46 Aquarium Fish Tank Bow Front 46L The Arc 46 features a curved front design, made of 4mm thick glass. Complete with built in filtration, so as to ensure the tank space is as free as possible, this 46l aquarium is ideal for freshwater, and with the addition of a heater, will be perfect for tropical fish. With a sleek lidless top, this comes complete with a glass lid that sit perfectly across the surface, giving a light and thin finish to the aquarium. The curved 10w LED with RGB light unit includes a blue moon feature, for optimum night time viewing in the evenings, so you can enjoy your aquarium for even longer. This not only perfectly matches the curve of the tank, but offers a dimmable option, so you can control the brightness of the lighting at the touch of a button. The built in filtration is hidden away in the back of the tank, ensuring it is discreet and doesn't tank up any swimming space for your fish, keeping the look of the tank clean and tidy, and there is even a space to hold the heater in there too, keeping that out of view as well.
