Introduction
There are about 25 genera with about 350 species.
They prefer the protected inner reefs and avoid the steep outer reefs.
Cardinalfish are primarily crepuscular or nocturnal schooling fish;
during the day they hide between hard corals, crevices and caves.
Depending on the species, they grow between 3 and 25 cm long,
although most species remain smaller than 10 cm.
