Signs of tropical fish before giving birth to small fish

Tropical fish will have some pregnancy phenomena that ordinary fish will have before giving birth to small fish. For example, the belly gets bigger and the fetal point becomes obvious. Every mother fish will have many eggs in her belly. Some eggs are very dark. If you look through the skin of the mother fish, it will be a black spot. The more obvious the black spots, the greater the possibility that the female fish will give birth soon. Before giving birth, the mother fish usually shows a hasty swimming phenomenon, and her tail often tilts up.

It depends on the species of tropical fish. Generally speaking, the mother fish can swim fast or stay still at birth. The most obvious performance is that as long as you see the protruding anus of the mother fish, you can fish out the young fish and separate them.

First of all, the process from fertilization to female fish production:

1. Every female fish has a black spot on her stomach. If you look carefully, you will find small eggs in the black spots.

2. If the black spots will get bigger and bigger (the belly will get bigger and bigger) after successful fertilization, it is obvious that the larvae are developing.

Generally, small fish can be born in 28 to 30 days.

4, the mother fish will have the habit of eating larvae, remember to separate after birth.

Second, the method of induced labor is:

Change the water, raise the water temperature to 1-2 degrees, and it will be produced within 1-2 days. But don't use this method often. If the water is changed too frequently and the water temperature changes too much, the fish will get sick.

Don't change the water for three days after the female fish gives birth, otherwise it is easy to get sick. If possible, put it in a separate jar, otherwise the small fish will be eaten by other big fish after birth. The more big fish, the higher the probability of eating.
