When breeding Chinese fighting fish, it is recommended to use water with water temperature between 25-28 degrees Celsius. If you want to breed, you need to use 26-27 C water. They are tropical fish, so they grow better in relatively high water temperatures. It has a certain cold tolerance and can tolerate water temperatures above 6 degrees Celsius. But will go dormant in cold water. Therefore, if you want to keep it well, it is better to use water between 25-28 degrees Celsius.
When raising Chinese betta, you don't have to change water frequently. If there is a filter in the tank, you can change the water every 10-12 days. Because the filter can help purify the water, the interval between two water changes can be longer. If there is no filter in the fish tank, you can consider changing the water every 7 days or so. This can help improve and maintain water quality, so that fish can grow normally.
Changing water for Chinese fighting fish is actually very simple. Before changing water for 2-3 days, tap water is taken out and exposed to the sun to remove chlorine. On the day of changing water, the temperature of tap water is dried to the same level as that of the water in the fish tank, and then about one third of the old water in the fish tank is sucked away with a suction pipe, and the fish manure and feed residues in the fishtank are sucked away. Slowly pour the new water into the fish tank to keep the water level consistent with that before changing the water.
