Good lookin frogs! Have you read the care sheet? In general, you will go broke feeding them crix and super worms. Also, those food items are not great for staple foods. They will likely love nightcrawlers (earth worms) and you can get them pretty cheap (make sure they aren't contaminated...scents for fishing, fertilizers from lawns etc.) I also use Dubia roaches. You are in the right place for good information if you are open for advice.
