Behaviour and Temperament

Peaceful, Active and Social

Black Medaka are generally peaceful and enjoy living with their own kind.

They spend much of their time exploring and swimming near the surface. A group can create beautiful, constant movement without the aggressive behaviour associated with many other colourful fish.
