Wow, okay. I've not had to do it, and didn't even know how, I've got a pacman that won't touch worms. The ones I've fed him live in a "colony" under the water dish lol. As for the toad, something to remember is theyour can go for a while without eating and can get stressed, but my toads, wild caught when freaking out after water switching, etc, would eat and calm down when offered food, and from day one were eager eaters of pillbugs and crickets, and easily adapted to dubias, with worms taking some coaxing, but in the the end they too were easily assimilated into their diet.
