Rubble Dwarfgoby

The Rubble Dwarfgoby (Eviota prasina) is a small, tropical fish associated with coral reefs, primarily inhabiting shallow waters from 1 to 5 meters (3 to 16 feet) deep, though it can be found as deep as 65 meters (213 feet). This species reaches a maximum length of approximately 3.1 centimeters (1.2 inches).

The fish has a translucent greenish body with 6 to 7 internal brown bars and red-brown spots on its head. Its scale margins are reddish-brown, and a notable dark spot appears at the base of the tail. The upper half of its caudal peduncle is marked with a large black spot. Males feature a distinctive prolonged and filamentous first dorsal spine.

Its dorsal fin comprises 7 spiny rays and 8 to 11 soft rays, while the anal fin includes 1 spiny ray and 7 to 9 soft rays. The Rubble Dwarfgoby has ctenoid scales, which are missing on the head, nape, breast, and pectoral fin base. Its pelvic fins are separated, with a thin membrane joining their bases.

The Rubble Dwarfgoby is found across the Indo-West Pacific, stretching from East Africa and the 🌊 Red Sea to the East 🇮🇳 Indian region, including 🇮🇩 Indonesia, the 🇵🇭 Philippines, and Palau. Its range extends north to southern 🇯🇵 Japan and south to Lord Howe and Norfolk Island. However, it has not been recorded on the Great Barrier Reef.

This species prefers habitats near shore composed of rubble and algal-covered dead reefs.
