Before tropical fish are bred, some female fish will be restless and swim a lot before giving birth, and they will try to drive other fish away and keep other fish away from them. At this time, many small partners are at a loss. What should we do? What are you going to do?
In the last half day of labor, the female fish will be seen swimming backwards continuously, making movements similar to defecation, which is actually a sign that the cubs are about to be born. In addition, the anus of the female fish will become very large. It is convenient for small fish to be born. It is best to keep the female fish in labor in isolation, which is convenient for saving the physical strength of the female fish, and it can also prevent the small fish from being eaten by other big fish.
Breeding of many tropical fish is clearly seasonal. The tropical fish living in the aquarium can hardly feel the change of seasons, because the constant temperature equipment in the aquarium ignores even the minimum water temperature difference between day and night, and the artificially controlled lighting time and intensity cannot objectively reflect the change of seasons. Under such circumstances, only those tropical fish that are not sensitive to seasonal changes will breed all year round. Such fish originally come from areas with indistinct seasonal changes, or after long-term artificial rearing, the ability to adjust the breeding cycle according to the season has been eliminated. nature. However, a considerable number of tropical fish still maintain their original living habits, and their breeding will be stimulated only when the environmental conditions of the aquarium just conform to such changing laws.
And if the small fry that have been bred are best taken out and raised in separate tanks, because the small fry or eggs are easily eaten by other fish, maybe the eggs that the mother fish worked so hard to lay, and finally there are no eggs. Several survived.
