Koi fish are often kept as pets in many households, and it is presumed that they are familiar with their owners. However, there is limited scientific evidence to support this presumption.

In one study, koi were kept in tanks with different owners, and it was found that the fish did not show any indication of associating with the owner who had been caring for them the longest. In another study, a group of koi were separated into two groups, one of which was introduced to a new group of koi.

It was found that the original group of koi did not show any indication of interacting with the new group of koi, even though they had been kept in the same tank. These studies suggest that koi fish are not particularly familiar with their owners, and that any apparent familiarity is due to the fact that the fish have been kept in the same environment.


It depends on a number of factors, such as the size of the fish and the size of the tank. In general, however, it is not recommended to put guppies with koi as they may become prey for the larger fish.
