Frostfin cardinalfish

The Frostfin cardinalfish (Apogon hoeveni) is a small, tropical marine fish prominently featuring a reddish body with a distinctive frosty or white patch on its dorsal fin, contributing to its name. Originating from the Western Pacific, including regions like Indonesia and the Philippines, it inhabits coral reefs. This fish possesses a typical cardinalfish body shape, being somewhat elongated with large, prominent eyes adapted to its nocturnal lifestyle. Despite its striking appearance, it is not particularly well-known or widely kept in the aquarium hobby.
