_th place in Biotope Aquarium Design Contest 2020

Volume: 175L
Dimensions: 90x65x30 cm
List of fishes: Rhinogobius szechuanensis, Trilophysa bleekeri, Belligobio pengxianensis, Opsariichthys evolans
List of plants: There are no plants in the habitat I described.
Description of decorations: In order to better restore the underwater environment of the habitat I described, the rocks and sand I used are all collected from the streams in this basin. As a practitioner in the service industry, I can only take a break on Monday. I have a group of friends who also take a break on Monday. We get together and explore in the wild river every Monday. When I saw this river for the first time, I was instantly attracted by the beauty scene in front of me. I snorkeled in the water and watched the underwater scene. The sun hits the water, the ripples in the water, and the fish swimming in the water, forming a beautiful picture.
Description of equipment: EHEIM professionel 3 filter, EHEIM streamON wave pump (4000L/h), Kessil 360x Tuna Sun 90w (6000k-9000K color spectrum) (2). In order to restore the turbulent flow of the river in the habitat, I chose to use a filter and a large-flow wave pump. Under their action, the water flow velocity is very turbulent. Under the illumination of the light, the ripples on the water surface splashed down the bottom of the tank, which is fantastic. Sometimes, I think the fish in my tank actually live in that stream.
Water parameters: My fish tank is placed at home and the water temperature is about 25 degrees. The water parameter is pH 7.6, GH 4


Description of the area surrounding the biotope: Mount Emei is located on the southwestern edge of Sichuan Basin in China, between 29°16′-29°43′ north latitude and 103°10′-103°37′ east longitude. It stretches for 23 kilometers and covers an area of about 154 square kilometers.

The annual average rainfall of Mount Emei is 1922 mm and the annual average relative humidity is 85%. The hydrological location of Mount Emei belongs to the Dadu river and Qingyi river water system, and there are 5 natural rivers in the territory, namely Emei River, Linjiang River, Longchi River, Shihe River, and Huaxi River.

The habitat I described is Fuwen River, a tributary of the Emei River, in Chuanzhu village. The Chuanzhu village is located in the northwest of Emeishan City, adjacent to Emei Mountain, which is known as the world’s natural and cultural heritage, with an altitude of 400-1400 meters. The forest coverage rate is as high as 91.1%, the internal ecological environment is good, and the vegetation coverage rate is high.

Description of the underwater landscape of the biotope: The water flow in the habitat is turbulent and the water depth is less than 1 meter. The water is clear and rich in oxygen. The bottom of the river is covered with huge pebbles and fragments of river rocks. The riverbed substrate is sandy, covered with dust and organic debris. Under the sunlight, the rocks are covered with algae, which provides an extra source of food for fish.

The rich oxygen content here makes fish like them very much. The small insects hidden in the algae become their main foods source. According to the surrounding fishermen, if you are lucky, you can see the Chinese giant salamander, a famous protected animal in China.

Description of the parameters of the habitat: The Emei River Basin has a subtropical humid monsoon climate, warm in winter and cool in summer, four distinct seasons, abundant rainfall, annual rainfall of about 1,500 mm, and annual average temperature of 18°C. The frost-free period lasts for more than 290 days, with little sunshine. The water parameters are pH 7.6 and GH 4.

List of fishes and invertebrates occurring in the nature biotope: Rhinogobius szechuanensis, Trilophysa bleekeri, Belligobio pengxianensis, Opsariichthys evolans

List of plants found in the nature biotope: There are no plants in the habitat I described.

Threats to the ecology: There is a village around this stream. Some villagers wash clothes in the stream, and some children will play in the stream with their parents and catch fish during holidays. There are also some nearby villagers who use nets to catch fish. I felt very uncomfortable seeing the damage to this river, but I couldn’t stop it. I only hope that this beautiful stream can continue to exist. All I want to do is to record this beautiful moment. I hope everyone can take care of the environment and this beautiful stream.
