During the day, aquatic plants carry out photosynthesis, releasing the oxygen needed by tropical fish and absorbing the carbon dioxide exhaled by tropical fish. In the process of growing, aquatic plants can absorb and digest fish manure and other substances harmful to fish. Some tropical fish also hatch their eggs on the leaves of aquatic plants. Around the aquatic plants is an ideal place for tropical fish. The water plants cover the bright light and create a comfortable living environment for tropical fish. Water plants can also play a role in purifying water and depositing dirt.
Most of the aquatic plants grown in China are imported from abroad and can be divided into four major categories:
1, submerged plants 1, rooting in the water, long stems and leaves in the water.
2. Emerging plants: Roots on the bottom of the water, long stems in the water, and the leaves above the water or floating surface.
3, floating plants: leaves floating on the water, roots, stems hanging in the water.
4, the middle plant: not rooting in the water, breeding and growth in the water.
