We compiled this FAQ page to answer many of the frequently asked questions we’ve been asked over the years of compiling information for this site.

Koi (Cyprinus carpio) are from the Cyprinidae family.


Well almost is actually crazy what Koi will eat everything from

lettuce to legumes and

worms to watches (personal experience there).

But really to look after your koi well you do need to feed them a balanced diet and generally if you don’t have the time to organise the food to go along with that yourself there are some great pellet options available.

There is definitely a bit of a difference between keeping Koi in a tank and a pond although generally speaking a tank is smaller than a pond.

So when considering the introduction of other fish species to your pond you really do need to think about a couple of key points?

Do you have enough space, how do they feed (are they a bottom feeders or surface feeders) what size are they in comparison to the Koi you already have.

All in all though most Koi species are pretty timid and tend to get on well with our fish, I say that mostly because they don’t eat them I have no idea if they really like each other or not..

I have found this website to be particularly helpful though

It only takes a quick search on google and you will find a number of places where you can buy Koi fish.

We mostly like purchasing our fish from local breeders, however there are also a number of stores that sell Koi online and many of these stores do a great job, I just suggest checking the star ratings of these store before you buy online.

There is nothing more disheartening when you open a package to find the new additions to your Koi Pond floating at the top of a bag.

Koi Fish can be as low as $1-3 per fish and go all the way up to Hundreds of thousands of dollars. But to get some really spectacular Koi Fish you really don’t need to spend too much. Generally $50 to $300 will get you a great Koi Fish.

As mentioned in FAQ “How much are Koi fish?” the price of a Koi fish can range from a couple of dollars all the way up to hundreds of thousands even into the millions allegedly the most ever paid for a koi was 2.2 millions dollars but that price has been converted from Yen to USD and translated into today’s money.

Each year there are about 50,000 to 60,000 koi fish bred and the top 50 are the only koi that sell for big dollars. They generally go for between $60,000 and $80,000.

Koi generally live for around 20 to 30 years. The oldest Koi on record was named Hanako (lived to be about 226 years old and died around 1977).

Most domestic Koi generally grow about 12 to 15 inches long.

Japanese Koi commonly grow 22 to 26 inches long.

Jumbo size Koi can grow up to 34 to 36 inches long.
