Asian Arowana

The Asian Arowana refers to several varieties of freshwater fish in the genus Scleropages. Some sources differentiate these varieties into multiple species, while others consider the different strains to belong to a single species, Scleropages formosus. They have several other common names, including Asian bonytongue, dragon fish, and a number of names specific to different varieties.The Asian Arowana is a large bony tongue fish that has several different varieties, including the Gold, Green, and Red Arowanas. The body looks like that of a Silver Arowana, with the dorsal fin set far back near the caudal peduncle. The fish is long and slender and moves with a gracefulness that brings beauty to any home aquarium. The mouth is big like a drawbridge and filled with many small teeth. Depending on the variety, its color can vary considerably, from an olive brown along the back with greenish to silvery sides and pale green finagle to a deep bronze and red. A red tailed variety is also available.

The Asian Arowana requires much the same conditions as the Silver and Black Arowanas. These fish are excellent jumpers, so provide a tight fitting canopy. In nature, Asian Arowanas are found in slow moving streams with lots of weedy plants. Provide a large aquarium with plenty of open swimming space.It is a carnivore and young specimens are very active and need a large variety of foods.

Favorite foods include feeder fish, mosquito larvae, tadpoles, large insects, and occasionally flakes and pellets.Asian Arowanas require no special water conditions except for well-filtered water. A pH slightly acid to neutral is appreciated, as is a common temperature between 21-27 degrees Celsius.All Arowanas are mouth brooders, the male incubating the eggs. One of the sexual differences is the males have wider and deeper mouths for incubating purposes.
