Scientific Name: Osteoglossum Bicirrhosum Common Name: Albino Silver Arowana, Silver Red Eye Arowana Adult Size: 36 inches Life Expectancy: 15 - 20 years Habitat: South America Minimum Tank Size: 180 Gallons Ideal Tank Conditions: Temperature Range: 75 - 82°F pH Range: 6.5 - 7.0 Water Hardness: 8 - 12 Temperament: Will eat smaller fish but is suitable for some communities of larger species. Diet & Nutrition: Earthworms, crickets, waxworms, and frozen and dried foods such as bloodworm, shrimp, mussel and pellets. Breeding & Spawning: Infrequently bred in captivity. This is a mouthbrooding species, but unlike with the asian species it is the female who cares for the brood. The fry remain with the female once they have hatched, leaving her mouth to forage. If danger approaches she will signal for the fry to return. Slowly the fry begin to spend more and more time away from the adult fish, until they are large enough to fend for themselves. Gender: Mature males have a longer anal fin. Males also have lower pectoral fins then females. They say that males will also have longer barbs on their mouths but that is debatable.
