Yes, you are right. But I feet the mazuri to my Three Toed twice a week or so. The other days I feed worms, bugs etc and then fruit and veggies. She eats anything you give her, but does love her mazuri.
My water turtule, I feed the regular trout food or rep. pellets.
The Three Toed gets the tortoise food cause my cherry head eats that twice a week too. They live together since they were hatchlings.
