1. How big can Mary fry grow in a month Mary fry grow about 2 cm in a month, and their growth speed is still very fast compared with other fish. Under normal breeding, they only need about 4 months to mature. However, their specific growth speed depends on the way they are raised and the living environment. Mary fry itself is at a critical stage of growth and development. If breeders can ensure that they live in a comfortable environment and have enough food, their growth and development will be faster, and they can grow about 2-3 cm a month. If breeders can't guarantee the stability of their living environment, their growth rate will slow down, and they may only grow 1-2 cm a month.
