Metriaclima pyrsonotos nakantenga island o morth male

What the O means "O" stands for Orange or Marmalade Cat (MC), which is a color morph. While standard males are light blue with dark vertical bars and a vibrant orange-to-red dorsal fin, an "O" male displays a mottled or blotched colour like females but with pink, and white/blue tints. instead of the standard blue-and-black striping. Quite rare in the hobby.
