# Large-Toothed Cardinalfish (*Cheilodipterus macrodon*)

**Taxon:** Cardinals (*Apogonidae*)  
**Conservation Status:** LC - Least Concern  


The Cheilodipterus macrodon, commonly known as the large-toothed cardinalfish or tiger cardinalfish, is a marine species belonging to the family Apogonidae. This species can attain a maximum length of 25 cm and is typically found at depths ranging from 1 to 40 meters. It is characterized by a white tail with grey outer rays and a white tail base.

The large-toothed cardinalfish is prevalent on outer reef slopes at depths of 4-30 meters. It inhabits caves and ledges within clear lagoon and seaward reefs, spanning from 0.5 to at least 40 meters, and is often observed hovering solitarily in midwater. While adults are generally found in pairs or small groups consisting of several pairs, juveniles tend to be solitary or in small groups. This species primarily feeds on small fish and reaches sexual maturity at approximately 8 cm in length.

Cheilodipterus macrodon is known for its mouthbrooding reproductive behavior and demonstrates distinct pairing during courtship and spawning. This species exhibits obligate monogamy, forming one-to-one pair bonds regardless of the abundance of resources. 

The distribution of this species is extensive, covering the tropical waters of the Indo-Pacific region and including the Red Sea.
