a few days after spawning. Map fish need to hatch 2-3 days after spawning to become small fish, but the specific time of hatching is closely related to the temperature of hatching. Generally speaking, the higher the water temperature when hatching, the faster the fry hatches, but when hatching fish, try not to exceed 30 degrees Celsius. Because the fry hatched at high temperature is prone to physical weakness, the normal incubation is generally between 28-30 degrees Celsius. When the water temperature is between 28 and 30 degrees Celsius, the fry usually hatch within 48 hours. If the water temperature is below 28 C, the incubation time will exceed 48 hours, and if the water temperature is lower, it may not be able to hatch.
? The time when a map fish grows up is closely related to the way it is raised. If the environment is comfortable and the food is sufficient, it only takes 18-20 months for it to grow up and reproduce. If they are raised in a poor environment, their adult life will be relatively prolonged. If the breeder wants to make the map fish grow up quickly, he should give them enough food. Usually, he can make more beef hamburgers to feed them. He can also choose some live baits such as shrimp, red worms, small fish and water fleas to feed them.
