Albino Silver Arowana (Osteoglossum bicirrhosum) also known as the Dragon Fish or Monkey Fish are strong powerful swimmers, and can be fairly aggressive at times. They are large, silver colored and large pearl-like silver scales across their entire body. Albino Silver Arowana spend most of their time swimming close to the surface of the water. However it should be noted that they are notorious jumpers. They need a large and wide space because when placed in a tank that is too small for them, they will repeatedly try to jump.
