Colouration is a dense mosaic of green

Sunburst Butterflyfish (Chaetodon kleinii) ENTRY and endlessly entertaining to watchThe Sunburst Butterflyfish is one of the most underrated fish in the hobby and one of the very few butterflies that genuinely earns the description beginner friendly. Its golden yellow body carries a pale front section, a bold dark vertical bar running through the eye, distinctively dark lips, and blue iridescence edging the dorsal, caudal, and anal fins, producing a colour palette that stands out beautifully against reef rockwork under any lighting.
