Blue Tongue Skink Diet Calculator
Estimate the right weekly food portion and protein-to-plant ratio for your blue tongue skink based on its age, weight, and activity — grounded in real-world keeper feeding practice.
Overview
The Blue Tongue Skink Diet Calculator helps reptile keepers translate vague feeding advice into a concrete, weight-based weekly plan. Blue tongue skinks are omnivores whose nutritional needs shift dramatically as they grow — fast-growing babies need frequent, protein-rich meals, while adults thrive on smaller, plant-forward portions a couple of times a week.
This tool is built for hobbyist keepers, new skink owners, and anyone who wants to move past guesswork. By factoring in life stage, body weight, activity, and current body condition, it produces a realistic portion size, a feeding frequency, and a protein-to-plant ratio you can actually plate up — the way experienced keepers genuinely feed their animals.
How It Works
- Select the life stage. This sets the baseline feeding frequency and how protein-heavy the diet should be.
- Enter current body weight in grams. Portion size scales with body mass, so an accurate weight matters most.
- Choose an activity level. A very active or breeding-recovery skink burns more energy and needs slightly more food.
- Pick a body condition. The calculator nudges portions down for overweight animals and up for underweight ones.
- Press “Calculate Diet Plan.” You’ll get total weekly grams, per-feeding portions, feeding frequency, and a plate ratio breakdown.
Formula Explanation
The calculator estimates weekly food as a percentage of body weight, then adjusts it. In plain language:
Weekly food (g) = Body weight (g) × Base % × Activity factor × Condition factor
The Base % reflects how much a skink eats relative to its size at each stage: roughly 9% for babies, 6% for sub-adults, and 3.5% for adults across a week. The Activity factor is 0.9 (low), 1.0 (normal), or 1.15 (high). The Condition factor is 1.15 (underweight), 1.0 (ideal), or 0.82 (overweight).
That weekly total is split across feedings based on stage, and divided into a protein/vegetable/fruit ratio — protein-heavy for babies, plant-forward for adults, with fruit always kept as a small treat portion.
Practical Benefits
- Stops over- and under-feeding. Obesity is one of the most common health problems in captive skinks; portion math helps prevent it.
- Makes prep predictable. Knowing grams per feeding lets you batch and freeze portions instead of eyeballing every meal.
- Right balance by age. Automatically shifts juveniles toward protein and adults toward greens, matching how needs change over time.
- Useful at vet visits. A clear weight-based feeding log gives your exotics vet something concrete to work with.
