Calcium daily. Calcium with D3 depending on what bulbs you are using and the amount of time they can get real sun should be given at most once a month. Vitamins never. Trioceros species are very sensitive to vitamin suppliments. Everything they get should come from gutloaded feeders.
I have been gut loading my crickets with flukers high calcium cricket diet gutload as well as zoomed natural cricket care and feeding them that organic spring mix salad and carrots all finely chopped in a blender. Should I still be giving calcium daily?
