How many is too many?

[AndyB]

Im currently housing 1 male Red-Eyed Tree Frog in an 18x18x24 exoterra tank, but I want to get another. There's two reptile/amphibian shows coming up this month in my area and im sticking to just Red-Eyes for now, but incase i get a little crazy and buy more than 1 (which is always a possiblility knowing myself :P ) I want to get an idea as to the maximum amount I can house confortably in this tank. I've gotten a lot of different answers off different websites, so I want to get opinions from people that have kept them. Thanks.

I haven't kept this species but in my opinion, 2, perhaps 3, is a safe maximum for that size terrarium.
