Can these frogs be kept together?

[BlueKiwiOca]

I just bought six new juvenile Green and Golden Bell Frogs to keep my frog company. I will be on selling a few of them, but I want to keep at least one to keep my first frog happy.

What I would like to know, is whether the size difference between these two frogs is too great, therefore introducing a risk of cannibalism, or whether I can safely keep these two frogs together



That's my thumb by the way, as a reference of size.. And I have quite small hands thank you!
