What are the symptoms of fish pregnancy?
1. Abdominal swelling
When a fish is pregnant, the first change that can be seen is the swelling of the abdomen. However, the swelling of the abdomen is not always a result of pregnancy, as ascites may also cause the belly to grow. If you want to distinguish between the two, just look at the posterior or anterior part of the swelling.
2. The fetal spot is obvious
Generally, when a fish is pregnant, its fetal spots will become very obvious, some of them will change color and will get bigger and bigger. The fetal spot is an important basis for judging the pregnancy of the fish, not only that, for experienced people, the size and color of the fetal spot can also determine whether the fish is going to spawn or give birth to small fish.
3. Loss of appetite
A fish does not show a loss of appetite immediately after pregnancy, but its appetite will gradually decline, and the worse its appetite is, the more it indicates that it is about to reproduce. The poorer the appetite, the more 在·it means that it is going to reproduce. At this time, you should prepare in advance by putting some water plants or other things into the fish tank so that the fish eggs can attach to it.
4. Hide in the dark
If there are some hiding places in the tank, the pregnant female fish will often go there to avoid the same kind of fish, especially the male fish. Usually when there is this kind of performance, basically the eggs will be spawned on the same day, so usually you must pay attention to observe the fish’s every move, so as to facilitate the care.
