Koi Fish Food – Nutritional Requirements For Your Koi

As with any living thing, food is one of the main factors of survival, growth, and development of pets. Knowing what proper fish food to feed your Koi will help ensure a lifetime of enjoyment and relaxation with your Koi pond.

Koi Fish


Water temperature greatly influences the appetite of Koi because they’re ectothermic – meaning their body temperatures adjust to their surroundings. The colder the water is, the lower the metabolism of Koi and the less food they will need. It’s okay to feed your Koi more than once a day if you live in a tropical country or during summer months. Otherwise, they only need to be fed once a day. In really cold weather when the water goes below 55 degrees F, all they need is to be fed a few times per week.

There are different kinds of fish food for Koi and the weather also determines what kind of nutrition they require. Pellets range from minimal protein (around 25%), high-carb content to high protein ones at 40% that contain color enhancers. The latter is the best food to give you Koi when the water temperature ranges from the lower 70s to 80 degrees F. You can feed them twice, maybe three times a day during this time. For variety, it might be good to give them fruits and vegetables as well as plankton. They’ll also love occasional treats like shrimp and silkworm pupae during the summer months when their appetite is strong and they’re eating ravenously.

During colder weather, Koi don’t really need that much protein and all they’ll need are supplemental, high-carb pellets and food such as cereal, vegetables and wheat bread. More processed white bread contains a type of bleach which can be detrimental to fish health. Gradually move to pellets with higher protein content as the weather gets warmer. A wide assortment of Koi fish food that have varying degrees of protein content are available at your local tropical fish shop or over the internet.

Pellets are generally classified into two types: floating and sinking. Since Japanese carp, like their predecessors have mouths that are angled downward, this means they’re bottom-feeders. Sinking pellets (held together by fats) last in cold water longer and are the perfect choice for such fish, but this means you won’t have a good view of your pets while they dine. Floating pellets which have undergone a process of streaming to give it a sort of shell, stay on the surface initially. You can watch your Koi more closely when you give them these. Floating-type Koi fish food are also a good way for you to let your pets get accustomed to your presence and associate you with food. This means it’s quite possible for them to follow you around while you’re walking next to the pond – loads of fun!
