Nice looking frog! Nightcrawlers aren't that expensive and are pretty easy to find (about 12-20 for $3-$4). A lot of bait stores carry them, as does Walmart. Also, if you can, I would recommend starting a roach colony. Free, never-ending food supply. I tong feed roaches to my adult pyxie and have no problem feeding him 20-30 in just a few miniutes. Superworms are also really easy to breed, but shouldn't be a staple. 3 mice a week is way too many, and way to expensive. Good luck.
