Hyporhamphus affinis, the tropical halfbeak, tropical garfish, insular halfbeak or coral reef halfbeak, is a species of schooling marine fish from the family Hemiramphidae. It is distributed through the Indo-Pacific regions and has been recorded in the Mediterranean Sea which it reached through the Suez Canal.
Hyporhamphus affinis has a blue back with a silvery stripe on side, silvery white underparts and a blue caudal fin while the other fins are colourless. They grow to a maximum length of 38 cm.[2] The distal half of the underside of the elongated lower jaw is bright red. There is a well developed anterior lobe on the dorsal fin and the caudal fin has a slightly longer lower lobe than the upper. The upper jaw is scaled, the pre-orbital region is much longer than the upper jaw.[3][4]
