What you Need to Know about a Koi Fish first days of life!
Regardless of whether you’re a koi breeder or a casual koi hobbyist, there are few things quite as fascinating as seeing koi eggs hatch and turn into big, healthy koi fishes.
If you’ve finally decided to breed your own koi or if you’ve decided to buy koi eggs instead of young koi, you’re probably wondering what you should expect when it comes to koi fish eggs and the first days of life.
But don’t worry because here’s everything you need to know about koi fish eggs and the first days of life.
The basics of koi fish eggs and the first days of life
To start off our discussion about koi fish eggs and the first days of life, let’s talk about first what koi fish eggs look like.
Koi fish eggs are tiny white, yellow, or green beadlike specks.
If you look closely through the transparent membrane, you will notice two black spots.
Those are the eyes of the koi fishes!
Koi eggs will typically hatch in less than a week so you wouldn’t have to wait long before seeing young koi fishes swimming about.
Under ideal conditions, koi fish eggs can hatch in just two days.
But take note that these two days are crucial, especially if the koi fish eggs are in the pond.
Some adult koi fishes enjoy snacking on koi fish eggs, so you either have to take out the eggs and incubate them in an indoor tank or watch out for roaming adult koi.
I highly suggest incubating the eggs in a tank since it will give you more control of the environment.
These koi fish eggs will eventually hatch into small koi fishes, referred to as koi fry.
Note that even koi fry can still be eaten by larger koi fishes, so it’s best to wait until the koi fry get a little bigger before introducing them into the pond.
After hatching, the koi fry will attach themselves to the sides of the pond and for the next few days, their own egg yolk will be their main source of nutrition.
After a few more days, the koi fry will start swimming and will be ready to eat koi fish food.
Take note, however, that since koi fry have small mouths, you have to feed them either liquid food or small particle koi food.
You can also feed your koi fry with hard boiled eggs or baby brine shrimp.
As your koi fry grow bigger, you can start giving them bigger solid food.
Koi fry are easy targets for predators in the early stages of their life, so you need to devise ways to protect them.
For example, you can add more floating plants and install caves in your pond to give your baby koi places to hide.
Watching koi fish eggs and the first days of life is certainly a fascinating experience.
But don’t get caught up in the moment!
Make sure that you know what to expect and how to properly take care of koi in their early stages to increase their survival rate.
