What is the Catfish Food Quantity Calculator?
The Catfish Food Quantity Calculator estimates how much food to feed catfish per feeding to avoid overfeeding. 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.
Expect roughly 5-15 years with a catfish, which is worth factoring into any long-term plan. They are an omnivore, so their nutritional needs shift with age, size and activity. Aquarium catfish range from 4cm corydoras to species over a meter, so confirm adult size before buying. Most are bottom-dwellers needing smooth substrate to protect their barbels and their own sinking food. Keep an eye out for barbel erosion from sharp gravel, starvation when assumed to be scavengers, ich. These are the conditions catfish are most commonly seen for.

How does the Catfish Food Quantity Calculator 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 catfish. It is a starting point, not a verdict. Somebody who has actually examined your catfish will always know more than a formula does.
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 Catfish Food Quantity Calculator?
- Enter the body weight in whichever unit you use (lb, oz, kg)
- Pick your activity level (Low, Moderate, High)
- Enter the calories per cup of your food
- Press Calculate, then read the result alongside the sources listed below
If two people care for your catfish, agree on one method and stick to it. Half of all confusing results come from measuring differently each time.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for catfish, but your catfish may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
