Raising methods

The American Kujian can be said to be a fish that does not deserve its name, because it does not come from the United States, and the pattern is not Kujian (but Tenjian). The American Nine prefers to live in clear water with abundant water flow and rich oxygen content. It needs a water environment with a pH of 5.8-7.8 and a water temperature of 23°C-27°C. They feed on the bottom, but are strong swimmers and can easily jump out of the water when excited, so they need to be covered for protection. In addition, the male American Nine is territorial and has obvious aggressive behavior towards fish with similar appearance. The penultimate black stripe of the American Nine is actually two when it is a juvenile (so it is Eleven at this time), and merges into one when it grows up.
