I bought a exo terra 12x12x18, its a bit small but it beats the dinky 10gal fish tank by far.

My question is will a red eye tree frog be comfortable in this tank? The local exotic pet shop owner said that I can and may even be able to get away with 2 of them in that tank. I would like a second opinion before I purchase a frog. and if 1 will fit would it be possible to get another later or would that make it to cramped?

Also I had a peacock ornate tree frog, I did a good job keeping him happy however an ugly divorced forced me away from him. Would a red eye be any more difficult to keep? I have researched the temp/hum reqs and will even be getting an auto thermostat and fogger to insure my frog is happy.
