The life span of Mickey fish is generally about 2-3 years. Compared with other fish, their life span is relatively short. However, their specific life span depends on the living environment and the way they are raised. If Mickey fish live in a comfortable environment and have enough food, their life span can reach about 3 years. If they live in an environment that is not suitable for them, and if there is not enough food, their life span will be reduced. Generally, they can only live for about 2 years, and some may live less than 2 years. In addition, too frequent production of Mickey fish will also reduce their life span, so breeders should try not to let them produce too many times.

If breeders want them to live longer, it is best to ensure that the living environment is comfortable and the food is sufficient, so that their physique will be stronger and their life will be longer.

Mickey fish is 3-4 cm in adulthood. They are small fish. Coupled with many hybridization and improvement, their body size is small, generally about 3 cm. If properly raised, the body length can reach 4 cm. If it is not properly raised, it may grow to 2 cm.

Mickey fish grow faster, and they can mature within 3-4 months of birth. At this time, they will stop growing, and the breeder can let them reproduce.
