Immature males look the same as females until they mature. Males get alot darker then. Either a molt or ventral sexing is the only way to identify sex....unless you have had it for 8 years or so. Then maybe you could assume it maybe a female. Males mature around 5-7 years. Mine matured at 6 years....my female is 9 years old.
