In the process of feeding, it can drop 65438 0 degrees Celsius regularly every day until the water temperature is kept at about 26 degrees Celsius. Then suddenly raise it to 33 degrees Celsius and keep it for a month. You will find that the head of the arhat fish will grow rapidly. When the head is satisfied, you can slowly restore the water temperature to about 28 degrees Celsius.
In order to stimulate the head development of arhat fish, the breeder can put a mirror next to the fish tank for a while every day to stimulate the aggressiveness and aggression of arhat fish and stimulate the head development.

Correct feeding method of arhat fish
1. Try to use a larger water tank (1 meter or more) to control the water quality and help the fish grow beautifully.
2. Fish have an excellent appetite and grow fast, so it is necessary to prepare an effective filtration system to ensure water quality and prevent fish diseases. Before using tap water, air exposure or water purification agent should be added to remove chloride and harmful substances. The water quality of pH7 and the water temperature of 28℃ are ideal environment for fish culture.
3. Add some oxygen-increasing equipment to increase the oxygen content of water and make the fish more energetic. In order to ensure the smooth growth of fish, it is necessary to prepare a set of safe insulation equipment and a water temperature meter which is convenient to monitor the water temperature.
4, add a little salt to the water, change the water frequently or regularly, twice a week, which can stimulate the rapid growth of fish.
5. Feeding Lohan feed should follow the principle of "eat less and eat more meals", feeding 2 to 5 times a day, and the amount of each feeding should be controlled within 5 minutes, so as to avoid leaving residue after eating and prevent gastroenteritis. The food is mainly frozen blood worms, supplemented by frozen shrimp and colored bait, which can achieve ideal results.
6. Turn on the light for 4 hours every day except normal light. The daily light can be controlled at 10 hour, which has a good effect on the health and color performance of fish.
7. Laying a layer of bottom sand in the fish tank not only contributes to the stability of water quality, but also contributes to the coloring of arhats, especially the colorful red sandstone. But be careful not to affect the pH of water, which will affect the growth of Lohan.
8. Sometimes Lohan is easy to suffer from white spot disease through the drastic change of water temperature, so in areas where the temperature cannot be stabilized above 25℃, it is best to install a thermostat in the feeding tank and set the temperature at around 28℃.
