Main Ecosystem: Lake; Lakes, rivers and reservoirs
Temperament: Predatory; Will eat any tankmates that can fit into its mouth.
Diet: Carnivore; Feeds on insects, earthworms, shrimps, small fish, frogs, and mice.
Care: Keep only with other fish which will not fit into its mouth. Sometimes aggressive to other species of fish. But, if fed a proper diet, usually will not harm other fish, as long as they do not become aggressive with the arowana. If keeping in a group of other Asian Arowanas, keep in groups of 5-6 similar sized fish. These fish do not tolerate each other very well, and thus keeping 2-3 together could be devastating. To keep an Asian arowana, a minimum tank size of 180 gallons, together with a tigh

Gender: Asian Arowana are difficult to sex, especially when they are still young. At full grown size, females are generally wider in the girth than the males.
Breeding: Being a male mouth brooder, the 30-50 relatively large eggs are taken into the males mouth. There they are developed, hatched, and carried until the yolk sacs have been absorbed. These fish have been bred in captivity. For the most part, they are bred in ponds on fish farms. However, on rare occassions aquarium tank breeding has taken place.
Variants: Some Asian arowanas often have what is called a spoon head, which is when the head of the fish is lower then the spine causing the back to be slightly arched. This characteristic makes the spoon head varity worth extra cash.
Comments: Though pugnacious with others of its own species, as well as other arowanas of other species, there are many just as easily kept tank mates that will suit this fish. Some being the larger fish of the knife family (feather fins), large tinfoil barbs, giant gouramis, multiple larger cichlids (cichlids should be of the same water parameters/requirements as the arowana), and larger Asian and South American catfishes.
This Arowana is very expensive, compared to the more common Silver Arowana and Black Arowana.
