The Silver Arowana, or Arahuana, is known by many alternate names, on occasion making identification tricky. Scientifically, it is most regularly called Osteoglossum bicirrhosum, but one may also hear reference to O. vandelli, or Ischnosoma bicirrhosum. A number of the group referred to as band fishes, the Silver Arowana is regarded as a true bony fish. Indigenous to the flood plains of the Amazon River Basin in South The united states, the Arowana can reach an intimidating 47 inches in the wild, and is regularly too much for all but the advanced freshwater aquarist to manage. It can live to tell the tale short times out of the water breathing air by utilizing its swim bladder.The Silver Arowana prefers a 250-gallon tank with a fine gravel bottom, loosely planted, and soft, peaty water with a variety of open space above for swimming. The aquarium will have to be fitted with a tight, heavy cover because the Arowana will jump, particularly when after prey.After breeding, the male Silver Arowana is responsible for carrying the large eggs in his mouth where they mature in 50 to 60 days. When young, these fish are easily harassed by more aggressive species such as Cichlids. Knifefish, large Plecostomus, Catfish, and Ornate Bichirs make good tank mates for the Silver Arowana.A carnivore, the Silver Arowana will eat other smaller fish, water fleas, mosquito larvae, in addition to freeze-dried ocean plankton, krill and pellet foods. Fish pictured here are representative of the species only.
