The lifespan of parrotfish is generally around 4 to 5 years, but the specific lifespan may vary depending on their varieties and living environments. The lifespan of ordinary parrotfish is usually between 4 and 5 years, while some special varieties like the King Kong parrotfish and the God of Wealth parrotfish can live up to about 8 years. However, parrotfish that have undergone artificial coloring or operations usually have a shorter lifespan, often only about 1 year.
The main factors that affect the lifespan of parrotfish include water quality, water temperature, feeding, and disease prevention. Keeping the water clean, maintaining a constant water temperature, providing a diverse range of feed, and doing a good job in disease prevention can all effectively extend the lifespan of parrotfish. For example, the suitable water temperature for parrotfish is 25 - 30 °C. A part of the water should be replaced every day to keep the water clean, and the feeding should be diverse and done at regular times and in fixed amounts.
To extend the lifespan of parrotfish, it's crucial to provide a stable and comfortable living environment. Maintaining a constant water temperature, keeping the water clean, providing sufficient nutrition, and doing a good job in epidemic prevention are all the keys to ensuring the health and longevity of parrotfish.
