Placing zebrafish in an overcrowded tank can also make your fish fight with each other.
An overcrowded tank provides no room for your zebrafish to swim, eventually making them aggressive and fight with each other.
In addition, an overcrowded tank can also affect the growth of your zebrafish, eventually leading to extreme stress in your fish.
Sick zebra danios in the tank
If you have a sick zebra danios in the tank, the other fish can attack the weak fish, thinking of them as predators due to the change in their appearance.
In such a case, you should place the injured fish in a separate tank to prevent your fish from passing away.
Are my zebra danios mating or fighting?
It is usual to confuse your zebrafish’s fighting and mating behavior.
Zebra danios mate by chasing each other. The male zebrafish chase the female to encourage her to lay eggs.
Once the female lays eggs, the male zebrafish fertilizes it by releasing its milt upon the eggs.
If your female zebrafish is appearing broader than usual and getting chased by the males, it is normal as this is how zebrafish mate.
But, if your female zebrafish is not carrying eggs and still getting chased by the male, it is a matter of concern as it is a sign of aggression in your fish.
We recommend you to take immediate action in such a case as ignoring such a situation can lead to physical injuries to your fish.
