Thank you Scott. For the ranitomeya ventrimaculata, if I were to feed him crickets, they would have to be pinheads of a few days only. The Ranitomeya ventrimaculata will reach about 1.5 cm when adult... If I am right, the breeder in question will give me the start up fruit flies for the frog, and I think they are wingless.

We have 4 other frogs which are all very happy on crickets, including our bumble bee walking toad.
