I have been wanting to get Red Eyed Tree Frogs and Gray tree frogs but I don't know if I can keep them together due to their individual needs. I have made a list of what they need and when I compare the two everything seems to be almost the same. The only thing I am unsure about is the size difference of the two frogs because a Gray Tree frog is about 2" while a Red Eyed Tree Frog is 2 1/2" to 3". If anyone has any experience with these two frogs please respond and tell me what I would need if this was possible.
