???? Ostracion cyanurus Feeding | Rare Footage of a Blue Boxfish on the Reef ????????

Ever seen a cube-shaped fish delicately grazing algae off coral rocks?
Meet the stunning Ostracion cyanurus, also known as the bluetail boxfish, captured in this rare underwater short as it feeds calmly on reef surfaces in the Persian Gulf.

???? Location: Kish Island, Persian Gulf
???? Camera: Olympus TG-6 + Macro Setup
???? Filmed & Edited by: @aqua_realm_

???? About the Species:
• Scientific name: Ostracion cyanurus
• Common name: Blue Boxfish
• Family: Ostraciidae
• These reef fish are known for their rigid, box-like body armor and striking blue tail.
• Mostly herbivorous, they feed by picking algae and small invertebrates off rocks and coral using their small, puckered mouths.

???? Why this footage is unique:
• Watching Ostracion cyanurus feed in the wild is rarely documented, especially this close.
• Its slow, calculated movements, vibrant coloration, and square-shaped body make it a true icon of the reef.
• Despite its clumsy look, it’s well-adapted for coral life — a living tank with surprising grace.
