The dottybacks are a family, Pseudochromidae, of fishes in the order Perciformes. Around 100 species belong to this family.
They are found in the tropical and subtropical Indo-Pacific, where they inhabit coral reefs. They are brightly coloured fish, often showing striking sexual dimorphism. They are generally small, mostly less than 10 cm (3.9 in) in length, and some less than 2 cm (0.79 in). They are distinguished from other families by the presence of three or less spines in the dorsal fin and an incomplete lateral line organ.
