Black / Blue Arowana (Osteoglossum ferreirai)


Found in blackwater stretches of the Rio Negro, upper Orinoco and Vaupes in South America, the Black Arowana (sometimes also known as Blue Arowana) is a sought after species due to its vibrant iridescent coloration and orange-trimmed black fins. Like their close cousin the Silver Arowana, they are large, powerful, surface-dwelling predators which require ample tankspace and a tight fitting cover as they are powerful jumpers. Black Arowana are generally peaceful towards any tankmates too large to be eaten, but territorial towards each other unless kept in larger groups. Although they reach a slightly smaller adult size than their close relative the Silver Arowana, they can still easily reach 20”+ as adults and require an appropriately large aquarium.
