Färbung

The body is typically dark grey to black, adorned with iridescent blue-green scales that form a reticulated pattern. A prominent black spot is often present on the flank, and another at the base of the caudal fin. The most striking feature is the bright orange or gold margin on the dorsal, caudal, and sometimes anal fins, which intensifies with age and during breeding. Males often develop a nuchal hump and elongated fin rays. Some captive-bred varieties exhibit more intense blue or white coloration, leading to 'White Saum' or 'Blue Saum' designations.
