Koi are a type of fish that are often kept in ponds or water gardens. They are a popular choice for many people because of their bright colors and patterns.
Koi are also known for their long lifespans, with some living for over 200 years.
One of the most common questions that people have about koi is why they sometimes stay at the top of the water. There are a few different reasons why this may happen.
One reason is that the koi is trying to get more oxygen. Koi need oxygen to breathe, just like we do.
When the water is warm, there is less oxygen dissolved in it. This can cause koi to surface more often to get the oxygen they need.
Another reason why koi may stay at the top of the water is because they are trying to stay cool. Koi are cold-blooded, which means that their body temperature changes based on the temperature of their surroundings.
When the water is warm, koi will often surface to try and stay cooler.
