Arowana is called AROWANA in its place of origin. The Chinese pronunciation is "AROWANA", which means "long tongue" in Spanish. Its scientific name "SCLEROPAGES" means tongue and hard pharynx. According to taxonomy, arowana belongs to the family OSTEOGLOSSIDAE (Osteoglossidae, also called Osteopharyngaceae).
Arowana, belonging to the family Osteoglossidae, is a large freshwater fish. It existed as early as the ancient Carboniferous period. The fish was first discovered in 1829 in the Amazon Basin of South America, and was named by the American ichthyologist Dr. Vandell. In 1933, French ichthyologist Dr. Belugalon discovered red arowana in Saigon, Vietnam. In 1966, French ichthyologists Blanc and Dobarton discovered another species of Arowana in Phnom Penh. Later, experts and scholars from some countries successively discovered other arowana species in Vietnam, Peninsular Malaysia, Sumatra, Banga Island, Bi Borneo and Thailand in Indonesia, so the arowana was divided into golden arowana, orange-red arowana, and golden arowana. Fish, platinum arowana, green arowana and silver arowana etc. The introduction of fish into aquariums as an ornamental fish began in the United States in the late 1950s, and it was not until the 1980s that it gradually became popular around the world.
The whole body of the dragon fish shines with cyan light, its large round scales glow pink when illuminated by the light, and its fins also show various colors. Different arowanas have different colors. For example, the juvenile red dragons in Southeast Asia have small red scales and reddish white. When adults, the edges of the gill cover and lingula are dark red, and the scales are shiny; the edges of the scales of the golden dragon, platinum dragon, and green dragon are golden yellow and white gold respectively. and cyan, among which those with purple-red patches are the most valuable. The main characteristic of this family of dragon fish is that its swim bladder is mesh-shaped and often has epibranchial organs.
Arowana is a carnivorous fish. From juvenile to adult fish, animal food must be fed, and it is best to feed small moving fish. Animal offal can easily damage the digestive system and should not be fed. The artificial compound feed for feeding is mostly shrimp feed (floating). I would like to remind you that fish need a variety of nutrients just like people. You cannot feed one kind of bait. You should develop a nutritious menu to ensure its nutritional balance.
The water temperature that Arowana can adapt to is between 24 and 29 degrees Celsius. If the fish adapts well, it can even adapt to temperatures of 22 and 31 degrees Celsius. However, like other ornamental fish, arowana should avoid drastic changes in water temperature.
