New green tree frog

[Canterthefrogman]

HI all,

I have a green tree frog who is really small, and I just went to the store and got a new one not knowing how big it actually was. Will the new one eat the other? Will there be any problems?

Thanks

P.S.
Sorry if this is a stupid question, I am new to keeping frogs.

As long as one is 3/4 of the size of the other, you will be fine. But if it's less, there is a good chance the big one will do it's best to eat the small one, and if the smaller one is half the size of the bigger, or less, you might as well rename it "Lunch". Time for a second tank?
