How Do Koi Carp Mate? 0 1511

If you keep a pond of healthy koi carp then sooner or later they will do what comes naturally and produce more koi carp!

This can be very rewarding for the koi keeper, as seeing the colors and varieties that your own koi produce can be very exciting! It is also a sign that your koi are living in good conditions and you are maintaining your pond well.

But how do koi carp mate? Read on to learn the basics of how koi mate and what signs you need to look out for.?

The basics of koi reproduction

Koi carp reproduce via a process of spawning, where the female koi will lay a large number of eggs.

How do koi carp mate?The eggs may be laid in various different areas of the pond, including on the base, on plants, and on the sides of the pond. Often, the number of eggs laid by one female can number several thousands, but not all of these will hatch into fry!

Once the eggs have been laid, the male koi will fertilize them, and the future koi will begin to grow and develop; if they are not eaten by the adult koi first!

The mating behavior of koi

There are several signs that your koi are ready to mate. You just need to know what to look out for!

The male koi are usually the most obvious to display the signs that mating is imminent, so keep an eye on your males for changes in their normal behavior. When they are ready to fertilize eggs, the mail koi will undergo some physical changes that are quite easy to spot.

The males will develop ?breeding areas? on their pectoral fins and head. These are sometimes mistaken for an illness known as ?Ich? by inexperienced hobbyists, as they can be quite similar in appearance.

The males will also begin to chase the females around the pond, which can be mistaken for aggression or bullying, but is in fact part of the breeding dance! The male will appear to head-butt or bump into the female repeatedly, in order to encourage her to release her eggs for fertilization.

When the female is ready, she will release her eggs around the pond, which the male will then fertilize.


It is not uncommon for adult fish to eat spawn and newly-hatched fry, so you might need to consider blocking off areas of the pond to prevent this, or separating the spawn from the main pond.

However, assuming that some of the fertilized eggs get the chance to grow and develop, you can expect your brand new baby koi to hatch anywhere between four and seven days after fertilization.

Keeping exotic fish as pets 0 1799

Exotic fish

There’s something mesmerising about watching a tank full of brightly coloured fish swim around. Do they make good pets though? Is it hard to keep exotic fish? With the right pet care and pet advice, exotic fish make great, if unusual pets.

Tank size

Go for the biggest sized tank you can afford and have room for. The bigger your tank, the easier you’ll find keeping the balance of the water right. Your fish need plenty of room to swim too. Aim for at least a 20-gallon tank.

Tank set-up

You’re going to need a heater to warm the water. You’ll also need a filter to ensure clean, healthy water, which is crucial for fish to thrive. It’s advisable to add an air pump to boost the oxygen levels.

You’ll also need a light for the tank, and a timer for the light, so it’s not on all the time. Bear in mind a fish tank should be placed out of direct sunlight, away from draughts and heating sources.

On top of the things that make your tank work you’re going to need everything that goes into your tank; gravel for the bottom, plants, and decorative caves and tunnels so your fish can hide if they want to.

You can usually buy aquarium starter kits at pet food stores if you want help in pulling everything together.

Getting the water right

The filter will cycle your water to make it suitable for fish to live in, never add tap water directly to the tank. You need to de-chlorinate it first. You can also add a water treatment to help keep the water healthy between changes.

You should change about 10-15% of the water each week to keep it clean and healthy for the fish. Never do a full tank change once your fish are in the tank.

Choosing your fish

When you choose your fish, make sure you start introducing them slowly – this will help you identify if you’ve got the water balance right, and at this point, your tanks eco-system is still developing, so adding lots of fish can damage it.

There’s a wide range of tropical fish to choose from – Cichlids, Betta and Swordtails are good starter fish, and are nice to look at. Never mix goldfish and tropical fish together.
