They all have basically terrible eyesight lol I wouldn't worry about calcium or vitamin supplements. They only way to really get them into the frog without the dust washing off would be to inject it into the feeders with a syringe. The pellets will contain a good amount of vitamins and what not, and nightcrawlers and crickets are your best bet for live feeders. Avoid mealworms unless freshly molted and Idk about isopods, i probably wouldn't bother.
