Apogon
Apogon, commonly known as cardinalfish, are a genus of fish in the family Apogonidae. They are found in tropical and subtropical waters worldwide, inhabiting a variety of marine environments, including coral reefs, rocky shores, and seagrass beds.
Characteristics
Apogon species are small to medium-sized fish, typically ranging from 5 to 20 centimeters in length. They are characterized by their elongated bodies, large eyes, and prominent spines on their dorsal fins. Their coloration varies greatly between species, with many displaying vibrant reds, oranges, yellows, and blues. Some species also have distinctive patterns or markings.
Environments
Cardinalfish are primarily nocturnal, hiding during the day in crevices, under rocks, or among corals. They are active feeders at night, consuming small invertebrates, zooplankton, and other fish.
Reproduction
Apogon species exhibit a unique form of parental care. The males of many species brood the eggs in their mouths until they hatch. The females deposit the eggs into the male's mouth, where they are fertilized and incubated for several weeks.

There are over 150 species of cardinalfish worldwide. Some of the most well-known include:
