Boeseman's Rainbowfish

Melanotaenia boesemani

Endangered

At very high risk of extinction in the wild in the near future.

Spotted something wrong?

Boeseman's rainbowfish is an atheriniform fish of the family Melanotaeniidae endemic to the Ayamaru Lakes on the Bird's Head (Vogelkop) Peninsula of Western New Guinea. The species was discovered by Dr Marinus Boeseman around 1955. It was later described by Gerald Allen and Norbert Cross in 1980, and introduced into Europe in 1982 by Heiko Bleher. From then on the species was bred in captivity for subsequent sale worldwide as an ornamental fish. According to the International Union for Conservation of Nature, it is an endangered species.

Fun facts

  • GeneralIts front half is blue and its back half orange, as though it were two fish.
  • It lives only in the Ayamaru Lakes and in Lake Aitinjo, twenty kilometres to the south-east: a tiny range that explains its Endangered status.
  • In the late 1980s some 60,000 males a month were exported from the Ayamaru region for the aquarium trade, and the Indonesian government eventually restricted it.
  • The specimens on sale are almost always drab juveniles: the adult colouring, with an orange rear half and a greyish-blue front, takes more than a year to develop.
