Bluecheek butterflyfish

Distribution : Red Sea and Gulf of Aden.

The masked butterflyfish adds a bright touch to the reef. Its life close to corals reveals feeding relationships that can be difficult to see at first glance. Following it with our eyes invites us to observe the small living surfaces making up the landscape. Its documented depth range is 1–20 metres.

WHAT DOES IT LOOK LIKE?

This butterflyfish has a yellow body that is rounded and flattened from side to side. Fine vertical lines run across its sides, and a grey-blue patch marks its cheek. Its elongated snout ends in a small mouth; the cheek marking and body lines distinguish it better than yellow colour alone.

WHERE DOES IT LIVE?

This butterflyfish inhabits coral reefs in the Red Sea and Gulf of Aden. Coral-rich areas provide feeding surfaces and refuges within reef structure. Its presence depends on suitable food and shelter; fish communities vary across a reef.

WHAT DOES IT EAT?

It takes coral polyps and may also eat small molluscs and crustaceans. Feeding takes place beside reef surfaces; the small mouth reaches small food items. The diet is established from references, not merely from a fish being filmed beside coral.
