Apogon maculatus, commonly known as the flamefish, is a species of cardinalfish from the Western Atlantic.

[2] The body of the flamefish is reddish-orange with small spots of black, and a large dark area on its tail.

[6] Due to its small size, the flamefish hides from predators within coral reefs.

[3] Since coral reefs have abundant resources, they have become a popular mating site for flamefish.

[2] Although, the male flamefish's mouth is relatively protective, stress may decrease its parental care.

[8] If felt threatened by another tank fish, the flamefish may remain dormant by hiding during the day.
