Barking Tree Frog male/female?

[LizardMama]

Isn't there a big size difference with Grey tree frogs and Barking tree frogs? How much bigger are the Barking tree frogs?

Barking Tree Frogs are slightly bigger than Gray Tree Frogs but they get along very well. My 1 Barker is very good friends/buddies with my younger Gray Tree Frog [Poco]
