Additional info: I always wanted to make a fish tank about Chengdu, I live in Chengdu, so I found the fish represented by Zacco Chenggtui. The origin of this fish is very rare. Several previous origins have not been found in recent years. Is it really as rare as the local panda? I got a couple of them 150 km from the original area. It seems very precious. So I asked people to get the panda’s excrement as sediment, not just for fun gimmicks, but a warning that many things need to be treasured, just like pandas. Local Gobiocypris rarus is well utilized by biological experiments and water quality measurements, which is a good contrast.

INFORMATION ABOUT BIOTOPE

Description of the area surrounding the biotope: This is the transitional zone between Sichuan Basin and Qinghai-Tibet Plateau, and also the interim zone across modern central city (Chengdu) and primitive natural ecological area (Tibetan area). It has more than 200 days of precipitation each year, with an average annual rainfall about 1800 mm. Rivers converge into Minjiang River. Stable temperature and great humidity contribute the Bamboo growth. There is the home land of panda. The bamboo leaves that pandas eat fall into the river,breeding the lives here. In monsoon, sunken trees and roots in mountainous areas were mixed with bamboo leaves and other substances to deposit in the bottom of the water, which contains enormous sandstone and gravel. Water temperature will not exceed 25℃ in summer. There used to be the home of giant salamanders, but they are now disappeared. There are also have large number of Schizothoracic, Zacco, Hemibarbus, Beaufortia and other Cyprinidae.
