During the summer, on hot and sweltering days, the Koi fish diet needs to be adjusted to ensure the best health and development conditions for the fish. You should reduce the amount of food for Koi fish, only feed the fish 2 times a day at times of cool weather such as early morning and late afternoon.

Koi fish feed in summer should have a lower protein content than Koi fish feed in winter. You can use low-protein foods or make your own food from natural ingredients such as: fresh fish (sardines,..), green vegetables (peas, lettuce,...) and fruits (watermelon, grapefruit, orange,...).

In addition, before feeding the fish, you should turn off the face suction device to avoid sucking the fish's food and set aside a few minutes to monitor the amount of food the fish eats. After the fish finish eating, if there is leftover food, take it out to avoid polluting the water source, which adversely affects the health of Koi fish. After that, you should pay attention to reducing the amount of food suitable for fish in the following meals to minimize the amount of food wasted.

When choosing fish feed, you should choose reputable fish bran companies in the market, to ensure the best health and development for Koi fish. Hopefully, the above sharing can help your Koi fish farming process. Good luck!
