Koi are not what you might consider a traditional pet, but they offer some of the same advantages. Koi can be a calming addition to an outdoor garden or an indoor pool or aquarium. Koi may look like large goldfish, but the two are only distant cousins. Koi are actually more closely related to the common carp. Here are several more interesting tidbits about these fish.
1. Koi were developed in Japan more than 200 years ago.
2. Koi can grow up to 2 to 3 feet or longer.
3. Koi are omnivorous.
4. Koi love company.
5. Koi may change color throughout their lives.
6. Koi can survive under a thin layer of ice.
7. Your veterinarian can advise you on how to keep koi healthy.
8. Most koi can live for at least 20 years.
