Sargocentron is a genus of fish belonging to the family Holocentridae, commonly known as squirrelfishes. These fish are found in tropical and subtropical waters of the Indo-Pacific region.
Common Names
Members of this genus are commonly referred to as squirrelfishes, due to their large eyes and often brightly colored bodies. Some species also go by specific names such as the "flame squirrelfish" (Sargocentron diadema) and the "red squirrelfish" (Sargocentron rubrum).

Sargocentron species share a number of defining characteristics:
- Body shape: Elongated and somewhat compressed, with a deep body.
- Head: Large eyes, a small mouth, and spines on the head.
- Fins: Two dorsal fins, the first with spines and the second with soft rays. They also have anal fins with spines and soft rays, as well as pelvic fins.
- Scales: Ctenoid scales, which are rough to the touch.
- Coloration: Often brightly colored with red, orange, or yellow hues, and can exhibit bioluminescence.
Environment
Squirrelfishes of the genus Sargocentron are primarily nocturnal, spending their days hiding in crevices and caves on coral reefs. They emerge at night to feed on zooplankton and small invertebrates. These fish are important members of the reef ecosystem, playing a role in controlling populations of other organisms.
