Zapogon
Zapogon is a genus of marine fish in the family Apogonidae, commonly known as cardinalfishes. These small, brightly colored fish are found in tropical and subtropical waters worldwide. They are typically nocturnal and exhibit a distinctive behavior of guarding their eggs, which they carry in their mouths.
Common Names
Zapogon species are commonly referred to as "cardinalfishes" due to their bright red coloration, resembling the robes of cardinals. Some species also have specific common names, such as the "banded cardinalfish" (Zapogon amblycephalus) and the "ocellated cardinalfish" (Zapogon frenatus).
Characteristics
Zapogon species are generally small fish, with most species reaching a maximum size of 10 cm. They have elongated, compressed bodies with large eyes and small mouths. The dorsal fin is composed of two distinct parts, a spiny anterior portion and a soft posterior portion. The anal fin is also spiny and is located beneath the second dorsal fin. The caudal fin is forked. The color of Zapogon species varies depending on the species, but most have a bright red or orange coloration with black or white markings. They have a unique behavior of guarding their eggs in their mouths until they hatch.
Environments
Zapogon species inhabit a variety of marine environments, including coral reefs, seagrass beds, and rocky shores. They are typically found in shallow waters, but some species may occur at depths up to 100 meters. They are often found in association with other fish species, including wrasses, damselfishes, and angelfishes.
Diet
Zapogon species are primarily carnivorous and feed on small invertebrates such as plankton, crustaceans, and worms.
