Why Betta Fish Fight Each Other

2:52 AM Posted by publisher

Betta fish fight to protect their territory, to ensure that they have enough food, and also because they want to be “king of the hill” when it comes time for them to breed. These are genetic traits, and you won’t be able to train your fish not to fight.

When you have two male Betta fish in the tank, they will “flare” at each other – (this means they puff up, flaring out their fins and gill covers, to make themselves look bigger and more threatening.) Often one fish will admit defeat and swim away, leaving the other male victorious.

When people began keeping and fighting Betta fish, aggression was bred into them, but over the last few years, this trait has begun to be bred out of them.
