so i think you might be talking about he Phyllomedusa hypochondrialis. this is the smaller of the tigerlegs the supers are like red eye size F- 3insv M-2 1/2 sv and i personally thing a 2 gallon is too small for anything the smallest tank i have is a 10 gallon and i go up to a 125. but i like very spacious natural looking enclosures i feel it's only fair to them and the reg tiger legs are kept differently than the supers. these pics are NOT mine but just a representation of the 2 the one on the bark is a tomop and the one on the leaves is a hypochon
