Description

The cardinal soldierfish is a small, bright red reef fish of the squirrelfish family (Holocentridae) of the western Atlantic and Caribbean. The species grows to about 15 cm and has a stocky, laterally compressed body with conspicuously large eyes, in keeping with its nocturnal lifestyle. By day it hides in deep recesses, holes and caves of coral reefs and is rarely seen; at night it emerges to hunt small invertebrates. The species has no commercial value and is harmless to humans.
