Datnioides

Datnioides is a genus of ray-finned fish belonging to the family Lobotidae. These fishes are commonly known as tigerfish, tiger perch or freshwater tripletails. These fishes are found in the rivers of southern Asia and new Guinea.

==Taxonomy== Datnioides was first proposed as a genus in 1853 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker, in 1876 Bleeker designated Datnoides polota, which was the same as Coius polota that Francis Hamilton had described in 1822 from the Ganges, as its type species. In 2000 Maurice Kottelat determined that the type species of the genus Coius, Coius cobojius, was a junior synonym of Anabas testudineus so Coius is a junior synonym of Anabas, with Datnioides being the correct name for the tiger perch genus. Historically this genus was classified in the monotypic family Datnioididae but the 5th edition of the Fishes of the World classifies this genus as one of two genera in the family Lobotidae, alongside the tripletails in the genus Lobotes, which it places in the order Spariformes. Some workers include Hapalogenys in the Lobotidae, while other authors place the genus in the monogeneric family Datnioididae, alongside the families Hapalogenyidae and Lobotidae in the order Lobotiformes in the series Eupercaria.
