What is the Axolotl Prey Size Calculator?
The Axolotl Prey Size Calculator calculates correct feeder insect size relative to axolotl size. 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.
A well-cared-for axolotl usually lives somewhere between 10 and 15 years. They are a carnivore, so their nutritional needs shift with age, size and activity. Axolotls are fully aquatic and stay in larval form for life. They need cool water of 16-18C, no strong flow, and either bare bottom or fine sand, since gravel causes fatal impaction. Keep an eye out for gravel impaction, heat stress above 22C, fungal infection. These are the conditions axolotls are most commonly seen for.

How does the Axolotl Prey Size 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 axolotls. It is a starting point, not a verdict. Somebody who has actually examined your axolotl 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 Axolotl Prey Size 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 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 axolotl 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.
