Starting and keeping pacmans on a worm and pinkie diet?...

[Lija]

welcome to the forum, so glad you do your research first!

if you don't want to do crickets, that's all right, they are not that nutritious anyway. you can do dusted as per Carlos recommendations pieces of nightcrawler as a staple when a frog is little with occasional wax worms, hornworms. Mice can be fed only once a month, but a frog can be totally fine without any mice ever. you can get pacman food and use it once in a while too.
my concern however is that you are saying you have a tank that is big enough, you should have a tank that is small enough for a baby

Frogs of the genus Ceratophrys are sit-and-wait predators, partially concealing themselves in the leaves of the forest floor and remaining motionless most of the time (Duellman and Lizana 1994). When prey approaches, the animal quickly attacks, usually swallowing the prey whole (Duellman and Lizana 1994). Ceratophrys ornata consumes primarily vertebrates; stomach content analysis of thirty-four specimens from Uruguay included 78.5% anurans, 11.7% passerine birds, 7.7% rodents, and 0.3% snakes, leaving only 1.8% as “other” (Basso 1990).

Interesting. I'd be interested to know what Lija and Colleen'll make out of this.
