Yes that is definately an American Green tree Frog I remember reading about them. When I first joined this forum I was told the read the care article for grey tree frogs http://www.frogforum.net/tree-frog-c...ysoscelis.html ... apparently they are similar in care... feeding and temperature wise hope that helps.

hes a cutie by the way

Oh and mine bath in there dish everyday and I mist the baby a few times a day. its there way of drinking threw therir skin apparently lol. and yes a move and new terrarrium might be causeing him stress... our Frodo barely moved till we got him a bigger tank 24" or taller high is ideal for any tree frog. Frodo lives in an 18x18x24 exo terra terrarium and will be shareing it once the baby gets bigger. they like vines or something to perch up higher in ...and some lick hideing places like plants and logs though mine only sits on it at feeding time. and spends the day up at the top as far as he can get next to the light.
