1. When raising parrot fish, you must first control the water temperature, which is generally 28°C. The water quality should be kept clean and hygienic. A quarter of the water should be changed every three days, and more slightly acidic soft water should be used. Use live shrimps as feed instead of river fish, otherwise it will affect their body color. Let it receive 1-2 hours of light every day, and keep it dark the rest of the time. If the fish is sick, the water needs to be changed and salt added to warm it up. In severe cases, medicinal bath treatment is required.

2. Water temperature and quality. Parrot fish are tropical fish and have strong adaptability to temperature. They can survive in waters of 20-30°C. However, if you want it to grow healthily, the temperature should generally be controlled at Around 28℃. If the water temperature is relatively low, its surface will fade, affecting its ornamental value. In addition, it likes slightly acidic soft water, which should be changed every three days, and the water should be changed about a quarter.

3. Feed the parrot fish. Do not choose river fish as the feed for the parrot fish. This will cause the color of the fish to become lighter and may also make it sick. Don't feed loaches either, as this food is difficult to digest. If live insects are often fed, the fish will be picky eaters and will not eat pellet feed. At this time, the feed needs to be changed slowly. If you want to make it brightly colored, you can feed it live shrimp or brine shrimp. Before feeding, it needs to be disinfected and the hard spines on the head should be cut off.

4. Appropriate lighting. If the light is consistent for a long time, the color of the parrot fish will also become lighter, so it should be allowed to bask in the sun. You can receive 1-2 hours of strong light exposure every day, and then switch to a darker environment. In addition to natural light, lights can also be provided, and the exposure time should not be too long. In addition, instead of using ordinary fluorescent lamps, you can use red light tubes.

5. Disease prevention. There are two common diseases of parrot fish, namely saprolegnia and white spot disease. Among them, saprolegnia is caused by bacteria. Generally, fish are easily eroded by bacteria after being injured. White floc will grow in the wound, which needs to be soaked with salt water. It can also be treated with drugs such as potassium permanganate. White spot disease is caused by the infection of white spot worms, and the disease can be effectively controlled by changing the water and raising the temperature.
