What is the Koi Feeding Schedule Planner?
The Koi Feeding Schedule Planner builds a daily or weekly feeding schedule for koi. Overfeeding is one of the most common and most preventable health problems in pets, while underfeeding a growing or active animal can slow development or sap energy.
Koi generally live 25-40 years when they are well looked after. Diet-wise they are an omnivore, which shapes almost every feeding decision you make. Koi are pond fish, not aquarium fish. They need a minimum of roughly 3800 liters, at least 1.2m depth for overwintering, and heavy biological filtration to cope with their waste output. Keep an eye out for koi herpes virus, ulcers and bacterial infections, anchor worm and fish lice. These are the conditions koi are most commonly seen for.

How does the Koi Feeding Schedule Planner work?
The estimate starts from a resting-energy formula based on body weight, then adjusts for activity level, life stage and, where relevant, the specific nutritional profile of koi. Individual koi vary more than averages suggest, so read the number as a reference point rather than a measurement.
What changes the answer
- Body weight: the single biggest driver of daily calorie needs
- Activity level: a sedentary indoor animal needs meaningfully less than an active or working one
- Life stage: since growing, pregnant or nursing animals need more energy per kilogram than a stable adult
- Spay/neuter status: which typically lowers metabolic needs somewhat
How do you use the Koi Feeding Schedule Planner?
- Enter the age
- Pick your activity level (Low, Moderate, High)
- Answer "Neutered or spayed?"
- Pick your feeding style (Measured meals, Food always available)
- Press Calculate, then read the result alongside the sources listed below
If the result looks wrong, check your inputs before you worry. Entering weight in the wrong unit is easily the most common reason a figure looks off.

Before you rely on this
This calculation assumes a healthy adult koi with no complicating conditions. Pregnancy, recovery from illness, medication and significant age at either end of the scale all change what is appropriate. When in doubt, the safest move is to take the number to a vet and ask whether it fits your particular animal.
