Tailspot Cardinalfish

Apogon dovii

The Tailspot Cardinalfish is a small, reef-associated species known for its distinctive red coloration and a prominent black spot at the base of its tail fin. The body height is about one-third of its total length, and it has large eyes, with the diameter exceeding one-third of the head length. This species closely resembles the Apogon imberbis, a similarity noted by its original describer, Albert Günther. This cardinalfish inhabits tropical marine environments, specifically within the Eastern Pacific region, ranging from Mazatlán, Mexico, to Peru. It is typically found in shallow waters, with most sightings occurring at depths shallower than 40 meters, and 90% of occurrences being at depths less than 30 meters. The Tailspot Cardinalfish is often associated with rocky reefs, where it finds shelter and food. In terms of behavior, the species is known for its mouthbrooding reproductive strategy, where distinct pairing occurs during courtship and spawning. The IUCN has assessed its conservation status as Least Concern. Divers encountering this species can expect a harmless and non-aggressive fish that adds to the diversity of reef life.
