Giant red tail gourami
Species of fish
The giant red tail gourami (Osphronemus laticlavius) is a large species of gourami belonging to the family Osphronemidae. This endangered fish is native to the Southeast Asian island of Borneo, where only known from the Kinabatangan and Segama river basins in Sabah, East Malaysia.[1][2][3] First described in 1992 based on an aquarium specimen,[4] its exact range was not entirely certain, leading some source to incorrectly also report it from Indonesia.[5]
The giant red tail gourami is not common; in a study of the Segama River that covered eight years only a few were caught,[6] and it may already have disappeared from the lower Kinabatangan River.[7] It is replaced in Brunei, Sarawak, and North, East and West Kalimantan by the closely related O. septemfasciatus (this species may also occur in Sabah, but that is unconfirmed).[4][8][9] The common giant gourami (O. goramy) occurs at least in Sarawak and West Kalimantan, but this species is possibly not native to Borneo, instead being introduced.[4]
