Yep, its a baby. its the vertical zoomed habitat. 18" high. It was recommended by another site I had looked at. Is that still to small for a young tree frog?

<edit> I am going to go buy a larger terrarium so as he grows I won't have to disrupt him later on by changing his habitat. I would prefer larger anyways to give him more room anyways. Several people Ive seen say on line that the 12x12x18 isn't near big enough, but for some reason some sites say they are good. I would rather be safe than sorry and have an unhappy little fellow.
