Banggai Cardinalfish Video Stock Footage
This species grows up to 8 centimetres (3 in) total length. It is easily differentiated from all other cardinalfishes by its tasseled first dorsal fin, elongated anal and second dorsal fin rays, deeply forked caudal fin, and color pattern consisting of three black bars across the head and body and prominent black anterior edges on the anal and second dorsal fin. The male can be differentiated from the female by a conspicuous, enlarged oral cavity, which is apparent only when they are brooding. This fish is an opportunistic feeder. Its diet includes planktonic, demersal, and benthic organisms. Copepods constitute the bulk of its diet. It serves as an important food source for several species of lionfish (Pterois spp.), the honeycomb grouper (Epinephelus merra), the crocodilefish (Cymbacephalus beauforti), the snowflake moray (Echidna nebulosa), the estuarine stonefish (Synanceia horrida), and the yellow-lipped sea krait (Laticauda colubrina).
