I got a red eye tree frog 3 days ago. All hes done so far is sleep on the glass.
I woke up this morning and he was sleeping on the ground so I thought maybe he was up trying to look for food.

How should i feed these types of frogs? For my others, i simply put in a cricket, as it walks by them they eat it.
But this is my first tree frog, so i dont know if the same goes for them.

So my questions are
What is the best way to feed the frog?
Should i keep him in his enclosure when i feed him?
Are pinhead crickets the right food, should i try fruit flies?

Ive only had him for 3 days, so ill still wait another 4 days before i start to get concerned with him not eating.
I just need to be sure im feeding him properly, let me know guys! Thanks!
