Red Arowana fish (Scleropages formosus) was known for their bright color. The color patterns were formed by the first and second ring of the scales. This research aims to examine the brightness level of S. formosus scales based on their age. Nine individuals of S. formosus were divided into 3 groups according to their age (1 year, 2 years and 3 years old). Samples consisted of 5 scales were collected from caput, dorsal, and caudal, respectively. The brightness level of the scales were measured by comparing them towards a modified color scaling paper. There were increase in brightness level of the first ring (17,93%) and the second ring (11,47%) of the scales. The brightness level of the scales were also found to be increased along with the fish age.
