Betta is not harsh on temperature, generally it can survive at 20 ~ 30℃, and the water temperature of 24 ~ 27℃ is the most suitable for its growth. The optimum pH value of water is neutral water, and the pH value is 6.5 ~ 7.2. It is best to keep the dissolved oxygen at 5mg/l under the condition of artificial feeding.

In addition, we should also pay attention to controlling the contents of some toxins in the water, and take residual chlorine 0mg/l, nitrite 0mg/l, nitrate 5mg/l, ammonia nitrogen 0mg/l and phosphate 0mg/l as the standards to test whether the water quality of your culture meets the needs of fish, and make timely adjustments to provide a suitable water quality environment for betta fish.

There are no special restrictions on the containers for raising betta fish, ranging from mixed fish tanks to glass jars. However, due to their aggressive nature, in order to avoid fighting, they are generally raised separately. If you want to raise two male fighting fish, atrix, and each one shows a magnificent posture, you can insert a glass or a non-toxic plastic plate in the middle of the fish tank, which can feast your eyes without hurting the fish. However, no matter what kind of container is used, some necessary decoration and equipment are needed to provide the best living environment for the growth of betta fish.
