Luohanfish belongs to the noble among tropical ornamental fish and needs careful maintenance. In the daily management work, special attention should be paid to the following aspects:

First, pay attention to the monitoring of water quality

Luohan is a kind of ornamental fish with high water quality requirements. Due to the large amount of food intake and the large amount of excrement, it is easy to cause the deterioration of water quality. It is necessary to observe the condition of the aquaculture water every day, and if any phenomena such as abnormal water temperature and water color and turbidity of the water body are found, corresponding measures should be taken in time. The changes of oxygen and other indicators should be grasped and adjusted in time according to the requirements of breeding Luohan.

Second, pay attention to observe the activity of fish

Pets Xiaobian said that the activity of fish reflects the adaptability of fish to the environment and its own and health situation. Observing the activity of the fish is also the work that must be done every day, mainly to observe the appetite and swimming state. In the case of normal fish activity, feeding and feeding should be carried out according to the principle of four determinations; if abnormal reactions such as inactivity in eating or inability to swim are found, the water quality should be checked in time to check whether the fish is sick. To find the problem as soon as possible, quickly find the cause, and solve it in time.

Third, pay attention to the adjustment of water quality

Water change is a necessary measure to ensure the quality of aquaculture water. Pay attention to the following points when changing the water:

1. It is fresh water to dry.

The tap water has been purified and treated, which is relatively clean, with stable water quality and convenient use. Now tap water is generally used to raise ornamental fish. . Because the tap water is disinfected with bleaching powder, the water content has free chlorine, which will cause damage to the fish. Before changing the water, it must be dried to fully volatilize the chlorine gas. Another function of drying the water is to reduce the temperature difference between the new water and the fish tank, so as to avoid the discomfort caused by Luohan due to the change of water temperature.

2. Regular quantitative water changes

Different species and specifications of Luohan fish have different requirements for water quality, so the frequency of water changes varies from fish to fish. For example, the Luohan of the pearl strain likes new water, so the frequency of changing the water is higher, and the water is changed every 3 to 4 days; the Luohan of the golden flower strain prefers to live in the older water, so the water is changed every 10 days or so. That's enough; Red Horse Liu likes to live in old water, so you only need to change the water every two weeks. The water change is divided into partial water change and full water change. Partial water change is generally enough to drop 30% of the total water volume of the fish tank each time. Usually, some new water is added as appropriate depending on the thriving water body in the fish tank.

3. It is to master the water changing skills

Water changing not only needs to replace some old water, but more importantly, clean the sundries in the water and remove the pollution source. Generally, when changing the water, the water circulation equipment should be closed, the water flow in the tank should be stopped, and the water should be kept in a static state, so as to remove all the feces and foreign objects in the bottom sand. Control the speed of adding new water, slow but not too fast.

4. While adding new water, closely observe the reflection of Luohan.

If you find that Luohan has shrinking head, dull body color, etc., stop adding water immediately. Continue to add new water after Arhat's discomfort is relieved.
