rest assured, there are crickets that small at pet shops. if he is very tiny, you can even go with 'pin-head' crickets, being very small baby crickets. get some calcium/vitD dust and put a couple crix in a container with dust, shake them around, and coat them, then let them into the frog enclosure. keep an eye so crix don't chew on frog, but hopefully your frog is pretty hungry by now.


maybe the term QT tank is misleading. i guess i would call it an 'observational time'. make sure he is eating and pooping and acting normal before you set up your vivarium.
