【Hanging Plant Stand】This aquarium waterscape decoration can fix hydroponic plants. When in use, it is hung and fixed on the edge above the aquarium wall of the fish tank, making full use of the space above the fish tank. 【Decorative Fish Tank】This aquarium decorative cup is convenient for observing the growth process of plants. The plants are fixed through the container so that they grow in the appropriate position of the fish tank. According to the growth needs of different plants, the substrate or base fertilizer can be filled inside the cup for growth and maintenance. 【Hook-type Hanger】This aquarium decorative cup has an acrylic hook-type hanger, which is double-fixed with a suction cup and can clamp the tank wall with a thickness of less than 1.5cm/0.6". The height of the fixed hanger cannot be adjusted; the height of the adjustable model can be adjusted within a range of 5cm/2.0". 【High-quality Material】The cup body is made of high-quality plastic, which is strong, corrosion-resistant and easy to clean. At the same time, the direction of the water cup can be adjusted, and installation and disassembly are very simple. 【Natural Ecological Circulation System】The small holes at the bottom of the water grass basket allow the roots of the water grass plants to grow out and sink into the water to absorb nutrients. This not only purifies the water quality, but also allows water and nutrients to penetrate into the roots of the plants to promote plant growth.
