Eritrean butterflyfish

[3] Eritrean butterflyfish are oviparous fish forming monogamous pairings during breeding.They feed on coral polyps, gorgonians, algae, polychaete worms and small crustaceans.These form a group of largely allopatric species sharing the overall color pattern of dark forward-pointing chevrons on silvery hues, (usually) a black-and-white crown spot and yellow to red hindparts to a stunning degree; they differ in the exact combination of hues and some small pattern details.But recognition of this would probably result in several other small or monotypic subgenera becoming justified, and the older Rhombochaetodon would be the more conveniently apply to the entire radiation.These might be members of the subgenus Exornator – the lineages around the spot-banded butterflyfish (C. punctatofasciatus) – and C. citrinellus certainly looks somewhat similar to these.
