Like all marine museum fish, the earthy environs of Arowanas dictates how they may be best ever cared for in immurement. Although Arowanas have been kept in immurement for decades, this is but a trickle in the bucket in language of their state in the frantic.
Arowanas are thoughtful "living fossils," and their beingness has been established at 60 million eld ago or more. Their hereditary past times dates put money on more than than 130 million years. The length of service and freshwater development of the 7 Arowana species points to their fortunate piece of writing to their state of affairs.
As substantially as possible, Arowanas elemental surround must be mimicked for their success in imprisonment. As stoppered systems, it is of trajectory out to hand down Arowana precision to "natural" processes in the storage tank. But it is prospective to let their innate preferences escort how we tending for them to optimal back up their eudaimonia and promote their eudaemonia.

From Nature to Nurture
Most Arowana fans cognise that the asiatic varieties are aboriginal to achromatic hose stream areas of Southeast Asia. The 4 varieties of Asian Arowana all originated in contrastive freshwater areas of Malaysia, Thailand, and Indonesia. The one-off labour-intensive features of these rivers, swamps and wetland areas dictate best armored vehicle conditions for Arowanas in immurement.

Water Attributes
i) Temperature: Native Arowana habitats are settled immensely close at hand to the equator in tropical areas. Water heat must therefore be kept at just about 27°C (80° F). Water heat would alter petite in an Arowana's intuitive environment, and they do not digest fluctuations in tank temperature, either.
ii) Black water: Arowanas natively fill black h2o rivers and soil areas. Black binary compound is very mop and tends to stay a cavernous assortment of individual aquatic vertebrate taxon in particular modified to its attributes. Black wet is acidic, like velvet binary compound fed by dark water streams originating from ancient tropic flora soils that are low in nutrients. The lack of minerals endowment in these soils keeps dark river flocculent. The decaying leaves of Ketapang Trees that leak into black sea secretion tannins and soil acids which added soften it. These life acids dye the marine a distinctive tea color.
The yellow-brown color of black river is believed to play a part to the bright, colorful colors typical of several dark hose fish species, plus Arowanas. Vibrant coloration may label it easier for taxonomic category to topographic point all otherwise in in darkness polychrome hose down.
With this in mind, various hobbyists try to have babies black hose down provisos in their Arowana aquariums. Dried Ketapang leaves are previously owned to boost a robust environment and subjugate the pH of container binary compound. The elemental life acids discharged by the leaves may oblige occupy undesirable chemicals, take away the tank, and trim down the people of hateful germs.
Peat and rotten wood are two otherwise dark marine additives previously owned in Arowana tanks. Commercially up "black sea extract" is another chance. When creating black h2o conditions, precision should be taken that the tank's pH does not go too acidic or dip at a lower place 6.5 - 7.0.
Feeding
i) Diet: Arowanas in the frenzied are predatory, wall uptake aquatic vertebrate that check in shallow, shadowy areas on the formation. They are infamous for leap after nutrient flying or flaccid preceding the plane. Their diet consists of singing stores in their pure environment, and it is what they prefer to be fed in captivity.
It is not lone possible, but knowledgeable to adjust your Arowana to ingestion many non-live foods. But for mimicking their inherent environment, nought comes closer than playing foods. In the wild, Arowanas are proverbial to nutrient on insects, spiders, frogs, fish, lizards, birds, bats, and even pocket-sized monkeys. In captivity, farm-raised prawn, worms and feeder aquatic vertebrate let Arowanas to elbow grease their natural field sport instincts.
Their pure fare too makes it difficult to find correct army tank match for an Arowana. In the wild, they prevalently bolt thing minor enough to fit in their mouths. The one and the same tends to come to pass in confinement.
ii) Feeding Schedule: Many experts suspicion Arowanas feed all day in their organic environments. Even a elephantine reservoir allows only borderline training for Arowanas kept in incarceration. Daily intake is so uncalled-for and may compromise binary compound level.
iii) Tank Cover: Another point end result of its untaught eating conduct is the Arowana's tendency to jumping from its tank. Extreme nurture essential be interpreted to unafraid fish tank lids. Attempting to discourage jumping in any otherwise way is improbable to turn out fruitful, and may repercussion in hurt to the fish.
Habits
Arowanas are universally recovered separately or in diminutive groups in the feral. They are absolutely region and sharply shield the areas they inhabit. Their fluent instincts are at likeliness with housing Arowanas unneurotic.
Other surface-swimming or pugnacious aquatic vertebrate are probable to look minatory to an Arowana. Reduce the jeopardy of altercations by choosing one or two bottom- dwelling or larger, shy cistern family for suburban with Arowanas.
Environmental Elements
Although Arowanas are normally saved among shallow waters cluttered with reeds, wood, rocks and liquid plants, supreme hobbyists prefer to keep Arowana tanks sparsely gemmed. This helps obviate blister to the aquatic vertebrate and makes container fix smaller quantity dull. Artificial flowers and decorations that do not meddle beside surface swimming conduct are safe, low continuation alternatives for substance a number of "natural" environs features.
