There are several quality pond filtration systems on the market today. Though the average specimen in captivity might live 25 or 35 years, an old koi named Hanako, from Mino province in Japan, has been shown to be over 215 years old based on analysis of her scales, and other 100+ year old fish are known from the same pond.
We are a family owned and operated ornamental goldfish and koi farm, supplying the pet industry with quality feeder common goldfish, rosie red minnows, Koi Fish fancy goldfish (including sarasa comets, shubunkins, red fantails, calico fantails and pond comets), koi and butterfly koi for more than eight decades.

But U.S. Forest Service fish biologists with the Lake Tahoe Basin Management Unit said they're well-acquainted with the big goldfish - several pounds and up to 4 to 8 inches long - living in the large freshwater lake along the border between California and Nevada.
Hundreds or thousands of fish would be kept in the same pond, and as early as 1000 years ago people noticed that a few of those fish had more attractive color mutations; some of those fish were spared the fillet knife and kept aside in personal garden ponds as living jewels Over time, more and more exceptional fish appeared, and in 1820's Japan these exotic-looking carp acquired the name nishikigoi and the art of koi-breeding was established.

Since Japan is where the art of raising koi first began, it makes sense that the most prized fish come from Japan where people have been honing their art for many centuries. Even though koi can survive in ponds that are 36 inches deep in milder climates, aim for a depth of at least 48 to 60 inches so that your koi can congregate comfortably at the bottom of the pond during the winter months.
Economical, pressurized pond filters are commonly used for smaller goldfish ponds and backyard water gardens. Many people unfamiliar with fish think Koi are nothing more than large goldfish.
