The process from pregnancy to birth usually lasts for about a month. However, the mother fish in different water temperatures, their production cycle is also different. If the water temperature is relatively high and can be maintained above 26 C, it will be able to produce in about 20 days. At lower temperatures, it takes 30 days to start production. As long as the feeding environment is good, and it is emotionally stable and not frightened, it can produce small fry in about 3-4 hours. If it is the first time for the mother fish to produce, the production time will be longer, possibly more than 4 hours. Some fish that give birth at night will continue to do so the next day. If it is disturbed by outside interference, the production time will also be prolonged.
Changes in water quality and temperature can stimulate female fish production to a certain extent. Changing the water quality by changing all the water, so that the mother fish enters a new environment, can stimulate it to give birth quickly. Or changing the ambient temperature. Raise the temperature to about 30 C, and then slowly cool down. Reheat when the temperature is as low as 20 C, and let the temperature rise and fall repeatedly. Fluctuating temperatures also allow it to give birth quickly. However, if the mother fish can produce normally, it is not recommended to stimulate it to give birth. Using the outside world to stimulate it to give birth quickly, it is easy to have dystocia or stillbirth.
