Form 1: divided into brown dorsally and yellow ventrally (margin between the two colors usually located at the midline, but the brown may sometimes extend lower leaving only the belly yellow); dorsal fin brown, all other fins yellow to yellowish brown; face brownish yellow; sometimes with a small black spot occurring at the dorsal region of the caudal peduncle. Form 2: divided into blue or brown dorsally (the blue pigment covering a much smaller area than the brown pigment in form 1, restricted to the region of the back and not extending to the midline).
