Description
Aioliops brachypterus is a small fish, averaging at 17 to 20 mm (0.67 to 0.79 in) in length, with a maximum length of 24 mm (0.94 in). It can be distinguished from other members of the genus in that its body has no scales. It has a rounded snout and short fins (in comparison to other Aioliops species, hence its name). The body is colored gray to pinkish with a bright yellow strip in the middle of the body from the snout to the beginning of the tail fin. The fins are bluish in color. The tail fin has a large dark spot at the base. Males and females have similar coloration but males are distinguished by having a darker head and back part and a wider yellow stripe; while in females the yellow stripe is thinner extends into the head beyond the gill openings. The pelvic fins are also longer in males.
