Im still learning about darts and not nearly as knowledgable as Paul and others but i can help a little. I know that dart frogs like it nice and cool from 65-75 degrees. A high quality digital hygrometer is essential to proper husbandry. The humidity should be over 90. A mist king or exo terra monsoon mister or repti fogger would help if you have trouble keeping the humidity high. A calcium powder and a separate multi vitamin powder would be ideal as well. Calcium every other feeding and multi vitamins once a week. Good luck!
