The tank introduced here measures W300×D300×H300 (mm); a popular small-sized aquarium size commonly known as the 30-cube. Despite this seemingly small size, it holds over 25 liters of water, so, considering future maintenance, choosing a filtration system with excellent filtering capacity is a wise decision. Here, we use the Super Jet Filter ES-150 Ver.2. The ES-150 Ver.2 has a flow rate of 3.5 liters per minute and can hold 1.5 liters of filter media, demonstrating high filtration capacity suitable for the 30-cube. Regarding water outflow, there are several options depending on the desired strength of the water flow. In this aquascape, we use the Lily Pipe Spin P-1, which produces a gentle water flow softened by its unique loop-shaped outflow. The gentle water flow produced by such a filtration system creates a scene where Potamogeton perfoliatus sway, offering a view unique to aquatic plants that reaffirms the beauty of Japanese native aquatic plants. The leaves, with their undulating edges and a sense of transparency, appear as if they were born from pristine water currents.  Potamogeton perfoliatus exudes a simple and welcoming charm. In contrast, the choice of Tucanoichthys tucano might be considered somewhat extravagant, yet for an aquarium system emphasizing luxury, it could also satisfy the desire for a prestigious fish species.
