No problem! Nightcrawlers are actually healthy enough to use as a staple. Wax worms are very high in fat, but make an okay treat. Also, just a though: based on your pictures your toad may be a Woodhouse's toad like mine. The stripe down the back made me think about it. The partoid glands(the long bumps behind the eyes) in Woodhouse's toads point slightly inward. Ill find pictures/diagrams later and link them in another post. If you live somewhere in it's range(a large chunk of the Middle of the US extending to Las Vegas. It also has a subspecies that extends into lower California called the Rocky Mountain Toad.
