Male specimens are roughly between 16 and 18 centimetres (6.3 and 7.1 inches) in total length (including tail), and their main colour is deep green with lateral white stripes and white lips. The female specimens are slightly smaller than the males, and have similar colouration. When the females are excited, they change colours quickly, becoming yellow-lemon with two spots of light blue, and one of red.[4] An average of both genders shows a total length of 16 centimetres (6.3 inches).[4]
