After about two years of breeding, the rat fish will have the ability to reproduce. After the eggs are laid and inseminated, it's time to hatch. Aft that eggs are inseminate, it is best to isolate the parent fish and then fish out the eggs to hatch separately. If the fish eggs stick to the sunken wood or other things in the fish tank, they can be washed out with a straw. Sometimes some of the eggs stick to the wall of the tank, so you can scrape them off with a blade, but you need to be careful. You need to pick out the eggs that have not been fertilized, and then put the eggs that have been fertilized in a separate piece.
When hatching fish eggs, water temperature is a very important factor. When the water temperature is 24-26 degrees, it will hatch successfully in about three days. At first, you can not feed, and then you can feed some egg yolk and other foods. When the small fish grow up, they can feed some live animals, such as fish and insects.
In the process of hatching rat fish eggs, the hatching time is affected by many factors. The most important factor is the water temperature, in a certain range, the higher the water temperature, the faster the incubation rate. Generally speaking, if the water temperature is between 24 and 26 degrees, the incubation time will take about 3 days; If the water temperature is slightly higher, it will take about two days to hatch. Of course, the water temperature should not be too high. Other factors, such as water temperature and dissolved oxygen, need to be controlled.
