They are nocturnal so feed after sunset or when you notice frog is awake. Night crawlers (without dye at Walmart's sports section) are a great food. If frog is small, can cut worms from pointy end in pieces same length as frog. Worms can also be dusted. Just rinse in dechlorinated water, pat dry with paper towel, cut if required, and dust

Also, remember to add supplements, CA/D3 2X and vitamins 1X on different days with skip day in between, good luck .
