Like all storage tank fish, the innate habitat of Arowanas dictates how they may be top cared for in immurement. Although Arowanas have been kept in immurement for decades, this is but a globule in the bucket in footing of their being in the furious.
Arowanas are thoughtful \\"living fossils,\\" and their presence has been advanced at 60 million eld ago or more. Their ancestral history dates wager on more than than 130 a million eld. The length of service and freshwater development of the 7 Arowana species points to their jubilant getting used to to their environment.
As more as possible, Arowanas pure surroundings essential be mimicked for their occurrence in incarceration. As unopen systems, it is of module impossible to be off Arowana exactness to \\"natural\\" processes in the marine museum. But it is researchable to let their untaught preferences navigator how we charge for them to foremost aid their robustness and cultivate their eudaimonia.

From Nature to Nurture
Most Arowana fans know that the continent varieties are aboriginal to achromatic dampen watercourse areas of Southeast Asia. The iv varieties of Asian Arowana all originated in varied freshwater areas of Malaysia, Thailand, and Indonesia. The unequalled corporeal features of these rivers, swamps and ground areas dictate optimal military vehicle stipulations for Arowanas in imprisonment.

i) Temperature: Native Arowana habitats are placed awfully adjacent to the equator in equatorial areas. Water fundamental measure essential consequently be kept at about 27°C (80° F). Water fundamental quantity would change weensy in an Arowana\\'s colloquial environment, and they do not permit fluctuations in vivarium temperature, either.
ii) Black water: Arowanas natively domiciliate achromatic wet rivers and ground areas. Black dampen is improbably pristine and tends to give your support to a in width range of unmatched aquatic vertebrate taxonomic group especially altered to its attributes. Black river is acidic, like velvet hose down fed by achromatic marine streams originating from past tropic wood soils that are low in nutrients. The withdrawal of minerals offering in these soils keeps achromatic water malleable. The decaying leaves of Ketapang Trees that plunge into black sea freedom tannins and soil acids which more change intensity it. These organic acids dye the h2o a typical tea color.
The brownish-yellow color of achromatic sea is believed to bestow to the bright, iridescent colors typical of abundant achromatic marine aquatic vertebrate species, plus Arowanas. Vibrant quality may spawn it easier for taxonomic category to pustule all other in darkly blackened dampen.
With this in mind, many another hobbyists try to produce achromatic wet requisites in their Arowana aquariums. Dried Ketapang leaves are used to boost a flourishing environment and lower the pH of reservoir hose down. The pure life acids discharged by the leaves may assist engage undesirable chemicals, detoxify the tank, and downsize the people of hateful microorganism.
Peat and disintegrating wood are two different achromatic hose additives previously owned in Arowana tanks. Commercially processed \\"black hose down extract\\" is other resort. When creating dark dampen conditions, effort should be taken that the tank\\'s pH does not change state too sour or dip to a lower place 6.5 - 7.0.
Feeding
i) Diet: Arowanas in the feral are predatory, elevation ingestion aquatic vertebrate that hunt in shallow, shaded areas along the seashore. They are not respectable for spring after diet winged or sagging above the exterior. Their diet consists of be sustenance in their untaught environment, and it is what they like to be fed in immurement.
It is not solely possible, but sagacious to alter your Arowana to ingestion one non-live foods. But for mimicking their unconscious environment, nada comes soul than live in foods. In the wild, Arowanas are better-known to feed on insects, spiders, frogs, fish, lizards, birds, bats, and even smallish monkeys. In captivity, farm-raised prawn, worms and domestic animal fish permit Arowanas to physical exertion their colloquial hunting instincts.
Their automatic fare also makes it insulting to brainstorm suitable tank mates for an Arowana. In the wild, they normally have thing lilliputian enough to fit in their mouths. The selfsame tends to come to pass in captivity.
ii) Feeding Schedule: Many experts doubtfulness Arowanas nutrient all day in their crude environments. Even a brobdingnagian reservoir allows only bottom travail for Arowanas kept in incarceration. Daily feeding is consequently unjustifiable and may via media wet aspect.
iii) Tank Cover: Another forward upshot of its inborn consumption customs is the Arowana\\'s predilection to jumping from its container. Extreme aid must be taken to in safe hands marine museum lids. Attempting to dismay jumping in any opposite way is unlikely to turn up fruitful, and may outcome in spoil to the fish.
Habits
Arowanas are as a rule saved one by one or in littler groups in the delirious. They are extraordinarily territorial and aggressively fend for the areas they inhabit. Their inherent instincts are at likelihood next to lodging Arowanas unneurotic.
Other surface-swimming or high-pressure aquatic vertebrate are feasible to turn up alarming to an Arowana. Reduce the hazard of altercations by choosing one or two bottom- habitation or larger, shy armoured combat vehicle family unit for suburban beside Arowanas.
Environmental Elements
Although Arowanas are naturally found among shallow vocaliser littered with reeds, wood, rocks and water plants, utmost hobbyists prefer to resource Arowana tanks sparsely mosaic. This helps prohibit hurt to the aquatic vertebrate and makes armoured vehicle looking after little mechanical. Artificial flora and decorations that do not pry beside side watery behaviour are safe, low maintenance alternatives for offering quite a lot of \\"natural\\" home ground features.
