fish in a few days after spawning. Zebrafish hatch small fish in about three days after spawning, but the specific time depends on the water temperature in the fish tank. If the water temperature is 24 degrees, the incubation time is 2-3 days. If the water temperature is 28 degrees, the incubation time is only about 36 hours. During the incubation period, the water quality must be maintained, if the water quality is poor, it is easy to fail to hatch. When hatching, it is better to fish out the unfertilized eggs and change the water every day.
zebrafish? 1. Water temperature: Although zebrafish do not require high water temperature, the newborn fish are fragile, so it is better to give them a constant temperature environment. The water temperature can be controlled between 21-23 degrees, and there should be no temperature difference when changing water.
2. Water quality: Zebrafish has no requirement for water quality, as long as the water in the fish tank is low in hardness and clear and clean. The best way to raise small fry is to change the water once a day, one quarter at a time.
3. Feeding: Newborn zebrafish carry their own nutrients, so they generally do not need to be fed for the first three days. Probably when the fry can swim by themselves, they can feed some egg yolk water. It can feed red worms, tubificidae and other foods in a week or so. When feeding, you need to clean up the live bait. The fry is relatively small, so it is recommended to cut them into small pieces before feeding them.
