Sargocentron caudimaculatum (Silverspot squirrelfish)

Sargocentron caudimaculatum can be found in the Indian and Pacific Oceans from East Africa to Japan and northern Australia and as far east as the Marshall Islands. It lives near reefs, but can also be found in lagoons and drop-offs at depths between 2 and 40 meters (6.6 and 131.2 ft). It is a nocturnal predator, feeding primarily on crabs and shrimps. It can reach sizes of up to 25.0 centimeters (9.8 in) TL. Although it is caught commercially and can be found in the aquarium trade, there are no known major threats to this species.
