Fighter fish or Bettas love floating plants and dim lighting. They also need access to open air above the water, as they are atmospheric air breathers. Periodically they take gulps from the surface. The labyrinth organ allows bettas to survive in very low oxygen. It has also led to Bettas being very overused in vases and cups, under the pretext that they will enjoy living in that way.
