Summary:
Colorful Qilin is a very popular ornamental fish with vibrant colors and auspicious meanings. However, to ensure its healthy growth, more patience and effort are required. Below, we will introduce some care tips for Colorful Qilin.

I. Water Quality Management
Water quality is the foundation for Colorful Qilin's growth, so regular water quality checks are necessary to maintain stable conditions. It's best to use professional filters and pumps to maintain water flow and prevent turbidity.
II. Light Control
Colorful Qilin prefers dim light environments; strong light can make them sick or lose their coloration. Therefore, direct sunlight on the water surface should be avoided, and appropriate lighting intensity should be maintained.

III. Suitable Temperature
Colorful Qilin grows best at around 25°C. Generally, if the water temperature falls below 20°C or rises above 30°C, it will affect their growth and reproduction.
IV. Feeding
Colorful Qilin are omnivorous fish that eat both fish food and insects. Feed amounts should be controlled, not exceeding about 2% of the fish's body weight daily. Balanced nutrition should also be provided.
V. Regular Water Changes
Regular water changes help maintain clean water and prevent harmful substances from accumulating. Generally, once a week is recommended. However, care should be taken not to disturb the fish during water changes.

VI. Careful Observation
Regularly observe the health status of Colorful Qilin. If abnormalities are found, they should be addressed promptly. For example, if fish develop a foul odor or white spots, immediate treatment is needed.
VII. Avoid Catching
Colorful Qilin are easily frightened fish, so catching should be minimized. Catching causes stress and may even lead to death. Therefore, frequent catching and moving should be avoided during maintenance.
VIII. Disease Prevention
Colorful Qilin are prone to common diseases such as ichthyophthiriasis and bacterial infections. Preventative measures should be taken by strengthening water quality management, proper feeding, and timely detection and treatment of problems.
IX. Appropriate Quantity
When keeping Colorful Qilin, pay attention to controlling the number appropriately and not exceeding the tank's capacity. Too many fish will cause intense competition, leading to slow growth and increased susceptibility to disease.
X. Compatible Tankmates
Colorful Qilin have strong territorial instincts and aggression. Different varieties may attack each other. Therefore, when choosing companions, select compatible species to avoid conflicts.
XI. Timely Dead Fish Removal
If Colorful Qilin die, they must be removed promptly to prevent affecting water quality and the health of other fish. Use professional tools to remove dead fish and clean filters immediately.
XII. Increase Oxygen
Colorful Qilin require sufficient oxygen. Insufficient oxygen levels will affect their growth and development. Oxygen content can be increased through enhanced water flow and using aerating equipment.
XIII. Healthy Maintenance
The healthy growth of Colorful Qilin requires comprehensive and systematic maintenance. We should regularly check fish health, nutritional intake, and provide better living conditions.
XIV. Pay Attention to Cleanliness
The environment for Colorful Qilin should be kept clean. Cluttered aquatic plants, oil films, or other contaminants on the water surface will affect growth, so filters and plants should be cleaned regularly.

Through these methods, we can better manage and care for Colorful Qilin. Of course, personalized care based on actual situations is also necessary to ensure their healthy growth.
