Your frog is a cutie .

Good food choices are crickets, dubia roaches, cut up worms when he is small. There are some other options as he grows. Purchase a calcium/vitamin D 3 amphibian powder and dust the food every other day by putting a pinch in a baggy and gently shaking the food in it. There are also amphibian multivitamin powders that can be sprinkled on their food once a week.

Congrats!
