The high water quality of arhat fish culture is because the life activities of arhat fish need sufficient oxygen and good water quality conditions. Generally speaking, the pH value of water should be kept between 6.8-7.6, the water temperature should be kept between 22-28℃, and the water flow should be kept unobstructed, so as to ensure that the oxygen in the water is sufficient. In order to ensure water quality, fish farmers can use filters, stagnant pools and aquatic plants to maintain good water quality conditions.

When raising arhat fish, water quantity is also a factor to be considered. Generally speaking, each arhat fish needs more than 2 liters of water, so as to ensure enough swimming space and a good living environment. Therefore, when choosing a fish tank, fish farmers need to consider the matching relationship between the number of fish and the size of the fish tank, and choose a suitable size fish tank to maintain good water quality.
3. Feed requirements
Luohan fish has a rich diet, which can be eaten with artificial feed such as dry food and bait, or with natural bait such as fresh fish, shrimp and shellfish. Fish farmers can choose suitable feed according to the growth stage and eating habits of the fish when raising the arhat fish, and also need to pay attention to the content and quality of the feed to ensure the health and growth of the arhat fish.
4. Environmental requirements

Because arhat fish is a gregarious fish, fish farmers need to ensure that the environment in the fish tank is harmonious enough to avoid fighting and attacks between fish. At the same time, the decoration in the fish tank also needs to be arranged reasonably to create a scene that conforms to the living habits and ecological environment of Luohan fish. For example, aquatic plants, rocks and other decorations can be added to enrich the environment of the fish tank.
