During the rainy season from April to September, the water level rises significantly. Soil, branches and leaves along the river banks are washed into the river. October to March is the dry season, the water level decreases, the amount of organic matter in the water decreases, and the water becomes clear. During the dry season, the typical pH is 6.3 and TDS is 32.

Underwater landscape

Fishes:

  • Oryzias pectoralis
  • Tanichthys albonubes
  • Barbodes semifasciolatus
  • Aphyocypris normalis

Aquatic plant:

  • Eleocharis yokoscensis

Wetland plants:

  • Phragmites australis
  • Nephrolepis sp.

The swamp I describe is rich in vegetation, with a large distribution of Nephrolepis sp. The swamp is littered with branches, providing plenty of shelter for fish. The substrate of the swamp is muddy, which is very suitable for the growth of Phragmites australis in it. In some areas of the swamp there is a distribution of Eleocharis yokoscensis.

Threats to ecology

Tanichthys albonubes is one of the most beautiful native fishes in China. Unfortunately, with the continuous expansion of human activities, the habitat is constantly being destroyed, and the wild population disappears a lot. In recent years, under the conservation of native guardians, the wild community is gradually recovering. The natural environment and underwater landscape of the habitat of Tanichthys albonubes are also very beautiful. In order to make people know about their life and protect them, I made this biome aquarium of Tanichthys albonubes. Since Tanichthys albonubes are protected fish in China, Tanichthys albonubes in my aquarium are artificial bred.

Comment by the expert

Fan Li: This biotope looks healthy and beautiful. The space structure was well designed.

Zhou Hang: A very natural BAM, almost exactly same as the biotope I am familiar with. Fishes are in good condition, well balanced and maintainable. Lighting is good too.
