A koi requires at least 3-4 gallons of water per fish and should be kept with at least one other fish in order to get the most out of their aquatic lifestyle.

Will koi outgrow a fish tank?

While it is impossible to predict the growth patterns of any given fish, it is generally safe to assume that koi will outgrow a fish tank provided that the tank is large enough and the fish are provided with enough space. Koi are typically considered to be swimming fish, so they will naturally want to move around and explore their new surroundings.

If the tank is not large enough, the koi may become congested and stressed, and may even start to fight with one another. Koi also require a fair amount of swimming space to properly navigate their environment.

If the tank is too small, the koi may not be able to reach all of the food and water they need, and may start to develop health issues.
