The Arowana, often referred to as the dragon fish, is a fascinating and visually striking species that has captivated aquarists and enthusiasts around the world.

The most well-known among them include the Silver Arowana (*Osteoglossum bicirrhosum*) and the Black Arowana (*Osteoglossum ferreirai*). There are about nine recognized species within the genus *Osteoglossum*, each with its own unique characteristics and habitats.
