Apogonidae
provided by wikipedia EN

Cardinalfishes are a family, Apogonidae, of ray-finned fishes found in the Atlantic, Indian, and Pacific Oceans; they are chiefly marine, but some species are found in brackish water and a few (notably Glossamia) are found in fresh water. A handful of species are kept in the aquarium and are popular as small, peaceful, and colourful fish. The family includes about 370 species.

They are generally small fish, with most species being less than 10 cm (3.9 in), and are often brightly coloured. They are distinguished by their large mouths, and the division of the dorsal fin into two separate fins. Most species live in tropical or subtropical waters, where they inhabit coral reefs and lagoons.[1]

They are nocturnal, spending the day in dark crevices within the reef. At least some species brood their eggs inside the mouths of the males.[1]

Classification

The 5th edition of Fishes of the World recognises only two subfamilies of the Apogonidae:[2]

Description
provided by World Register of Marine Species
Chiefly marine. Some in brackish water; in streams (tropical Pacific Islands). Distribution: Atlantic, Indian, and Pacific oceans. Dorsal fins separate. First dorsal fin with 6-8 spines; 8-14 soft rays in the second. Spines in anal fin 2; soft rays 8-18. Scales usually ctenoid; several groups with cycloid scales (absent in Gymnapogon). Branchiostegal rays 7. Vertebrae 24 or 25 (10 + 14 or 15). Many are mouthbrooders. It is suspected that in some species the incubation of eggs is done only by the males or by the females. Most species below 10 cm.
