Where does Astronotus Mikoljii come from?

This new species of cichlid of genus Astronotus lives in the Orinoco River and Gulf of Paria basins in Venezuela and Colombia. Researchers from Brazil and Venezuela used an integrative taxonomy approach, combining morphometric, otolithometric, and molecular data, to describe it.

Astronotus mikoljii inhabits the middle and lower reaches of the Orinoco River and the Gulf of Paria basin, at altitudes up to 250 m a.s.l. It lives in lotic or lentic water bodies,large or small rivers, culverts, lagoons, and floodplains, with white, clear, and black waters.

In its first stages of development, it is associated with floating vegetation and semi-rooted plants formed mainly in grasses and water hyacinth. In the adult phase they are located in riparian zones, generally among grasses and sedges.
