Bluestripe Squirrelfish

Sargocentron tiere is a species of squirrelfish in the genus Sargocentron, native to the Indo-Pacific. It inhabits coral reef and rocky coastal environments, where it typically shelters in crevices during the day. Like other squirrelfishes, it is primarily nocturnal, emerging at night to feed on small crustaceans and other invertebrates. The species is distinguished by its reddish body marked with blue horizontal lines and its large eyes, an adaptation to low-light conditions. It occasionally appears in the aquarium trade and can grow to 33 centimetres (13 in) in length.
