How this works for aquatic pets: We use a percentage-of-body-weight method — no calorie counting needed. Just tell us the food type and number of animals.
For a whole tank, enter the total number of fish. We'll divide the daily portion.
These are typical average values. Use "Enter from label" to match your exact product.
Look for "Calorie Content" or "Metabolizable Energy (ME)" — usually near the ingredients list on the back or side of the bag or can. It reads something like "3,500 kcal/kg" or "350 kcal/cup". Match the toggle above to whichever unit your label shows. Can't find it? Use the list option — it's accurate enough for most foods.
We'll subtract this from the daily food portion.

About the Sulcata (African Spurred) Tortoise
The Sulcata is the third-largest tortoise in the world, reaching the size of a coffee table — a grassland grazer that needs huge amounts of grass and hay and almost no fruit or protein. A typical adult weighs about 1–45 kg.
What to feed
Most common pet tortoises (Hermann's, Russian, leopard, sulcata) are herbivores that thrive on high-fibre weeds, grasses and leafy greens, with calcium supplementation and limited or no fruit. Grassland species especially need grass and hay, not fruit or protein.
Tortoises are typically fed daily or almost daily on a large volume of low-energy, high-fibre plants — they graze rather than eat rich meals. Feeding rich foods causes fast, lumpy shell growth (pyramiding).
Frequently asked questions
What do Sulcata tortoises eat?
Grasses and hay make up the bulk of a Sulcata's diet, with some leafy greens and weeds. Fruit and protein cause fast, lumpy shell growth (pyramiding) and should be avoided.
How big do Sulcata tortoises get?
Sulcatas can exceed 40 kg and live 70+ years — a serious long-term commitment. Their diet must be high-fibre grass and hay to keep their large shells growing smoothly.
What do tortoises eat?
Mostly high-fibre weeds, grasses and leafy greens with calcium supplementation. Grassland species (Russian, sulcata, leopard) especially need grass and hay; fruit should be limited or avoided.
