Blue neon goby with electric-blue lines — side profile over a pale reef floor

This underwater photograph shows an elongated blue neon goby in side profile, facing left. Its silvery body is crossed by highly contrasted electric-blue lines that continue across the head and accent the large translucent dorsal fin. The fish rests above a pale seabed made of sand, coral fragments and small textures, with softly blurred turquoise water behind it. The image suits editorial content about small reef fish, blue markings and close marine-life details.
