If you have your own Koi pond or have just inherited one after moving home, there is loads of information that you need to know so you can keep your fish healthy.

Koi diet and growth

There are quite a few things that can effect Koi growth, the most notable of which is the environment in which they are kept. Other notable additions to this are their diet and the fish’s genetic make-up.

Pond size

The size of your pond will have a real impact on the size of your fish. If you have a large pond with a large surface area and only have a small quantity of fish then of course your fish will be able to grow larger. It is worth noting that the fish will only grow to the space permitted by the pond area.

If you overstock your pond you will create competition between the fish which will affect their size negatively. Also if you have a small quantity of fish in your pond the stress they will feel will also be minimised meaning they will be able to grow much larger in size.
