Priocharax nanus
Dr Ralf Britz (Museum of Natural History London
A team of international fisheries group lead by Dr Ralf Britz (Museum of Natural History London) has published the description of a new species of fish found in the Rio Negro, the Amazon region of Brazil.

Rio Negro is a rich habitat of small fish, which are considered miniatures of other fish.

The fish was found in a stretch,where the water is like black tea and is higher acidic than ain water, at a pH of 4.5 - 5. This habitat is similar to the peat swamp in Indonesia where the world's smallest fish
was discovered in 2006; the Paedocypris progenetica species.

The new species is named scientifically as Priocharax nanus. In Latin it means Nanus is a dwarf, referring to the small size of this species as an adult.

In genus Priocharax it stood in third place, two species before it is Priocharax ariel and Priocharax pygmaeus. But, the biggest difference is the new fish pectoral fins and bones are not made up entirely of cartilage.

Sci-News Journal said Priocharax nanus is no longer than 15mm and a miniature bearing characteristics of other species. It is a semi-transparent fish (opaque), so easy to evade predators.

The full text scientific articles were Dr Ralf Britz for the journal Neotropical Ichthyology.
