Samples were measured length (11.1 – 25.9 cm) and weighed between 25.594 - 166.647 g. The fish’s metric and meristic characters, relationship between total length and other morphometric measurements, condition factors were determined as well. C. labrosus distinctively by its depth as pupil diameter, four spines in first dorsal fin, mean while the second fin has a single spine and 8 rays, thick upper lip, 9 rays in anal fin.
