Like all tank fish, the natural environment of Arowanas dictates how they may be highest cared for in confinement. Although Arowanas have been kept in imprisonment for decades, this is but a dewdrop in the bucket in status of their being in the manic.
Arowanas are thoughtful "living fossils," and their attendance has been established at 60 cardinal eld ago or much. Their heritable earlier period dates rear more than 130 cardinal age. The length of service and freshwater development of the 7 Arowana taxonomic category points to their winning accommodation to their environment.
As more than as possible, Arowanas pure home ground must be mimicked for their success in incarceration. As shut systems, it is of trajectory undoable to resign from Arowana guardianship to "natural" processes in the storage tank. But it is prospective to let their inborn preferences trailblazer how we tending for them to unsurpassable sponsorship their form and market their eudaemonia.

From Nature to Nurture
Most Arowana fans cognise that the continent varieties are domestic to achromatic sea river areas of Southeast Asia. The four varieties of Asian Arowana respectively originated in various freshwater areas of Malaysia, Thailand, and Indonesia. The incomparable sensual features of these rivers, swamps and ground areas rule optimal tracked vehicle provisions for Arowanas in imprisonment.
Water Attributes

i) Temperature: Native Arowana habitats are set incredibly adpressed to the equator in tropic areas. Water fundamental quantity essential and so be kept at in the region of 27°C (80° F). Water fundamental measure would alter puny in an Arowana's unprocessed environment, and they do not stand for fluctuations in storage tank temperature, either.
ii) Black water: Arowanas natively inhabit black dampen rivers and wetland areas. Black h2o is extremely speckless and tends to taking up a nationwide potpourri of unique aquatic vertebrate species particularly modified to its attributes. Black river is acidic, pulpy binary compound fed by dark liquid streams originating from ancient tropical vegetation soils that are low in nutrients. The denial of minerals contemporary in these soils keeps black dampen squishy. The decaying leaves of Ketapang Trees that spill out into black dampen giving off tannins and soil acids which further change intensity it. These natural acids dye the marine a distinctive tea color.
The chromatic colour of black marine is believed to join to the bright, glittering flag true of many black water aquatic vertebrate species, together with Arowanas. Vibrant color may trademark it easier for taxonomic group to stigma all new in in darkness red wet.
With this in mind, heaps hobbyists try to breed black water terms in their Arowana aquariums. Dried Ketapang leaves are utilized to boost a flourishing situation and lower the pH of container hose down. The raw organic acids discharged by the leaves may support involve hateful chemicals, remove the tank, and decrease the people of unenviable bacterium.
Peat and rotten wood are two otherwise black liquid additives used in Arowana tanks. Commercially prepared "black sea extract" is other picking. When creating black h2o conditions, attention to detail should be understood that the tank's pH does not change state too acidic or dip down below 6.5 - 7.0.
Feeding
i) Diet: Arowanas in the uncontrolled are predatory, exterior ingestion aquatic vertebrate that search in shallow, murky areas on the formation. They are not respectable for jumping after silage winged or hanging above the surface. Their fare consists of on stage hay in their inbred environment, and it is what they like to be fed in confinement.
It is not simply possible, but prudent to alter your Arowana to consumption whichever non-live foods. But for mimicking their inherent environment, naught comes human than live foods. In the wild, Arowanas are celebrated to feed on insects, spiders, frogs, fish, lizards, birds, bats, and even littler monkeys. In captivity, farm-raised prawn, worms and feeder aquatic vertebrate allow Arowanas to exertion their instinctive outdoor sport instincts.
Their unprocessed diet as well makes it insulting to brainstorm opportune reservoir family unit for an Arowana. In the wild, they usually wolf anything undersize satisfactory to fit in their mouths. The aforesaid tends to come to pass in imprisonment.
ii) Feeding Schedule: Many experts doubt Arowanas nutrient all day in their fluent environments. Even a heroic armored combat vehicle allows solitary negligible exercise for Arowanas kept in confinement. Daily feeding is for this reason unessential and may compromise binary compound characteristic.
iii) Tank Cover: Another unswerving development of its natural consumption conduct is the Arowana's mental attitude to leap from its armoured vehicle. Extreme nurture must be understood to immobilize marine museum lids. Attempting to prevent jumping in any remaining way is supposed to turn up fruitful, and may consequences in unhealthiness to the fish.

Arowanas are ordinarily found individually or in minute groups in the delirious. They are completely region and aggressively maintain the areas they inhabit. Their crude instincts are at probability near construction Arowanas both.
Other surface-swimming or predatory fish are promising to be sinister to an Arowana. Reduce the chance of altercations by choosing one or two bottom- domicile or larger, shy armored vehicle match for built-up near Arowanas.
Environmental Elements
Although Arowanas are naturally found among shelfy waters littered next to reeds, wood, rocks and hose down plants, maximum hobbyists prefer to keep hold of Arowana tanks sparsely buttony. This helps disqualify trauma to the aquatic vertebrate and makes tank repair less dull. Artificial vegetation and decorations that do not meddle near phony watery conduct are safe, low maintenance alternatives for offer some "natural" environs features.
