Average Medaka Lifespan and Factors Affecting Longevity
Wild medaka typically live 1-2 years, while in captivity they average 2-3 years. With optimal conditions, it's not uncommon for individuals to live 4 years or more.
The main factors affecting lifespan are:
- Water Quality: Water contaminated with ammonia or nitrite damages internal organs
- Water Temperature: Sudden temperature fluctuations or prolonged high temperatures cause significant physical stress
- Stress: Overcrowding and predators cause chronic stress that weakens the immune system
- Nutrition: Unbalanced diets or overfeeding burden the digestive system
- Genetic Factors: The degree of selective breeding affects the fragility of the fish's body
Captive medaka tend to live longer than wild ones because they have no predators and receive consistent food. In other words, a medaka's lifespan largely depends on the owner's care.
