In the past, my frogs have all been willing to eat food from my hands, including halves of dead crickets when I ran out of tiny ones. I just had to wiggle them a bit.

IF he will eat them can he? There's not like, some weird difference that makes them dangerous?

And, knowing me, I would fall in love with the roaches. One of my most beloved pets was a Madagascar Cockroach named Hisser. I had him for 6 years and cried for days when he died. I'd end up starving the poor frog just because I didn't want to feed him my cute baby roaches. I have a bad enough time with crickets and almost always have one or two special ones who are being kept as pets if there are crickets at my house. I'm a sucker. That's why I have 26 pets. And I don't know how they all find me! After I cleaned the froggy up, the first thing I said was HOW DO THEY FIND ME?! I think they know I will take care of them.
