One such example to make humans feel as if they are a part of Mother Nature’s ecosystem is by building a pond in a corner of their homes.
These dew ponds can have a variety of fishes living in them, but the most popular choice that tops the list of marine preferences is the Koi fish – also known as Nishikigoi.

Koi Fish Feeding Tips

Some other things to consider to ensure that your koi live a healthy life and they aren’t swimming around in poor water quality.
- Feed them protein-rich treats bought from the store or homemade once or twice a week. These include silkworm pupae, tubifex worms, tadpoles, mosquito larvae, and bloodworms to ensure that they reach the necessary protein consumption for their optimal growth and development. When you feed your Koi these treats not only are your koi going to love you even more but they are going to be getting some of their much needed amino acids.
- Regularly feed your Koi by hand. They are intelligent fishes and will know that you’re their benefactor in a small amount of time. Once you have established a connection, they will constantly chase you around the pond and will often greet you when you approach.
- If you have an ecosystem pond, then feeding your Koi is an option that will give you enjoyment. Watching them forage and hunt their own food in this environment can promote exercise and install foraging habits. Just ensure that they have enough room to occasionally forage on their own.
- Give your Koi foods rich in carbohydrates in spring and late fall, while protein-rich food should be provided in the summer.
- Koi have a long fasting period capacity because they can slow down their metabolism especially in winter. Thus, you can feed them in a much smaller amount than usual, to prevent water contamination and overfeeding.

Should I feed koi Sinking or Floating food?
Sinking Versus floating food
Generally speaking Koi foods are either floating or sinking.
Generally speaking Koi food is either Sinking or floating…
Simple I know…
Sinking koi food does exactly that, it sinks and just like the titanic it drops straight to the bottom.
This makes it an excellent choice for bottom feeders (What are bottom feeders – they are fish that swim along the bottom of a pond, lake or stream, gobbling up mouthfuls of whatever is down there then spitting out whatever doesn’t taste like food).
But when you feed your koi it is an entirely different matter.
Because we are talking about display-quality koi fish that can cost hundreds or even thousands of dollars, you most likely want to see these living jewels.
I am guessing that you don’t want them lurking in the deep dark sections of your pond gorging themselves!
After All that is not why you bought them!
So, when you feed your koi floating food that simply increases your opportunity to enjoy your treasure trove of colors that make up your school of Koi Fish.
On the Other hand though When you feed Koi this way it is also practical for three reasons:
It’s a great way for keeping track of how much food your koi eat and just how much food you put into your koi pond.
Secondly when you feed koi this way the food spreads out over the surface of your pond, which in turn gives your koi fish a chance to feed.
There is nothing better than interacting with your fish pond jewels as you feed koi. It genuinely gives you a chance to interact with your koi fish, while also seeing who’s feeding and who isn’t, and to check the health of your school to see who may have scale or other health issues.
