Getting enough food?

[Jace]

Okay-for the second time in one day, I cleaned and did Poe's tank. Poor frog is going to be stressed out for the rest of the day! I included some pics; a water dish is currently being sanitized and not yet in the enclosure.

Now-what is the best way to feed him? And are pinheads the way to go or should I try two week old crickets? Some of those can be quite small and may be easier for him to hunt.....
