hello... i just got my first pacman a month ago. it was the size of a golf ball when i got it and now he's more than doubled his size. is there any easy way to make sure of its sex? i'm planning to buy a partner soon so i need to know which to get. he is green with black markings on the back without any red or brown markings. there are also black markings on the underside of his jaw. does this mean he's a he? he doesn't croak yet even when i mist him but there was this one time when it made a sound when it got irritated when i was carrying it? do females also do that when they get irritated? hope to hear from you experienced froggists. thanks
