In the wild, Betta fish have been known to jump pool during the hot dry seasons in an attempt to find adequate bodies of water.

If you are seriously thinking of adding a Koi betta fish to your existing aquarium collection, or if you want to upgrade from your solitary Koi betta tank with other exotic aquatic life, it is important to consider the following factors:

This action will reduce his aggressive behavior towards other fish, and the Koi betta will not feel that his territory is being invaded, and attack the other fishes right away.

It also helps the Koi betta fish to integrate better. Suitable tank mates for the Koi betta fish must possess the following traits;



Must be peaceful

Aquarium Care of Koi betta fish

Care of Koi betta fish is no different from that of other bettas. Betta fish care is simple, and beginners can keep Koi betta fish as pets provided strict care guidelines are followed.

Tank water should be maintained accordingly; soft and warm regulated to imitate tropical conditions. Tank design should include a lot of plants to provide shade and hiding spots.

Like all bettas, Koi betta fish has a unique respiratory system known as the labyrinth organ. This special organ allows it to breathe directly from the water surface.
