can Mary fish grow? Mary fish can grow to 5-8cm. Because they are small fish, their body length is generally not too long. Mary fish in the wild are not the same as domestic fish. In the wild, Mary fish can reach about ten centimeters in length. However, for the average family, Mary fish can reach a maximum length of about eight centimeters.
For the average home breeder, they can reach the body length of adult fish in about three months. At this time, from the appearance, they are the same as adult fish, but the internal structure is different. Their sexual organs are not yet mature, so they can not reproduce. When they are about four months old, they are fully developed and have the ability to reproduce. If you want Mary fish to grow faster and stronger, you should feed them high-nutrient food, such as mealworms, red nematodes, water fleas and other fresh live baits.
is the life span of Mary fish? The life span of Mary fish is relatively short. Generally speaking, Mary fish in captivity can live for about two years without any disease. With better feeding conditions, Mary fish can survive for three years. Mary fish, which survive in the wild, are less restricted in their growth and live longer, with most individuals surviving for five years.
