When do medaka fight?

See the answer

During a turf war

The main reason medaka fish fight is territorial disputes. Especially during the breeding season, males may fight other males to secure breeding grounds. This behavior is seen in many other animals as well and is one of their natural instincts. Changes in food or water temperature are not direct causes of fighting; the primary causes are territory and breeding issues.
