I have a juvenile ornate, about 2 inches long, that I feed every two-three days. He'll eat about 6-8 medium-sized crickets in one sitting, though he wants more, i do not let him over-eat! i use vitamin powder every third feeding, because a growing frog needs the xtra calcium. my big old adult, Benne the albino cranwell, only needs to eat once a week. she'll take about 5-6 nightcrawlers in one feeding or 10 crix.
