When the mother fish is about to give birth, she can swim quickly or stay still. The most obvious performance is that you can fish out the larvae to be separated as long as you see the anus protruding from the mother fish. The mother fish will have the habit of eating larvae and remember to separate them after giving birth.
Generally speaking, the fertilized female fish can give birth to young fish within 28 days, but in summer, the pregnancy will be shortened by about three weeks. When the female fish wants to give birth back, some special features can be used to put the female fish to be born in the litter box: the mother fish's stomach is swollen and square at the fetal spot.
Extended data:
First, the process from fertilization to production of female fish:
1, every female fish has a black spot on her stomach. If you look carefully, you will find that there are small eggs in the black spot.
2. If the black spots will become more and more prominent (the belly is getting bigger and bigger) after successful fertilization, it is clear that the larvae are developing.
3. Generally, small fish can be born after 28 to 30 days.
4, the mother fish will have the habit of eating larvae, remember to separate after birth.
Second, the method of inducing labor is:
Change the fresh water and raise the water temperature to 1-2 degrees, and it will be produced in 1-2 days. But don't use this method often. Fish will get sick if they change the water too often and the temperature in the water changes too much. After the female fish gives birth, don't change the water for three days, otherwise it will get sick easily. If possible, put it in a separate tank, otherwise the baby fish will be eaten by other big fish after birth. The more big fish, the higher the probability of eating.
