UNS Rimless Cube Aquarium
Equal sides on every face, from a tiny 16 cm cube up to a 60 cm cube that holds over 200 litres. Cubes pull the eye to the centre of the layout, so they work well for a single strong focal point or a row of matching tanks.

Best for
Betta and shrimp tanks, centre-focused layouts, or a gallery of small cubes side by side.
Worth knowing
Cubes are deep for their width, so the larger ones need a strong light to reach the substrate and long tools to reach the back.
