Hello everybody!

I want to start bowl feeding my whites but im not sure how much bowls i would need.
I have 3, 4 month old whites tree frogs (Australian Green Tree Frogs) and i currently tong feed them.

So, if i have one bowl, would one eat all the food available or will it eat a few until its full and leave the rest?

I am currently feeding crickets but am going to feed them roaches.

Thanks guys!!!
