Fishes are a paraphyletic group and for this reason, the class Pisces seen in older reference works is no longer used in formal taxonomy.Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes: [1]
Fishes of the World is a standard reference for the systematics of fishes.It was first written in 1976 by the American ichthyologist Joseph S. Nelson (1937–2011). Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science.

Fish of this family are important as food in several regions, and also constitute a large percentage of captive freshwater aquarium fish species. [3] These fish vary in length; many are less than 3 cm (1.2 in). One of the smallest species, Hyphessobrycon roseus, grows to a maximum length of 1.9 cm. [4] These fish inhabit a wide range and ...
