The Asian arowana (Scleropages formosus) comprises several phenotypic varieties of freshwater fish distributed geographically across Southeast Asia. [3] While most consider the different varieties to belong to a single species, [ 4 ] [ 5 ] [ 6 ] [ 3 ] [ 7 ] work by Pouyaud et al. (2003) [ 8 ] differentiates these varieties into multiple species .
Asian arowana is an endangered species and banned in the United States. It is a status symbol among wealthy Asian men. An albino arowana sold for a record price of $300,000 in 2009. [8] Most pet arowana are farmed behind high-security fences. Arowanas are solitary fish and only allow company while young; adults may show dominance and aggression.

The Asian and Australian arowanas in the genus Scleropages separated about 140 million years ago, during the Early Cretaceous. [12] [13] Originally, it was thought that the breakup of Gondwana 150 – 30 million years ago was the evolutionary cause of the trans-continental distribution of the osteoglossomorphs. However, minimum ages of ...
