Classification of Arowana
Classification of Arowana
Arowana are freshwater fish early and not much evolved since the time of dinosaurs exist on earth! They aro Osteoglossidae including two more areOsteoglossum (South American Arowana) andScleropages (Arowana Asia and Australasia). Arowana scales to, close up and long, first elected shaped knife with a pair of antennae at the tip of the lower jaw are pointed out in front are said to have perceived functional changes in the water.
Arowana suitable for warm environment, tropical climate, temperature 23 to 30 degrees C, pH 6-7 (6.5 is the most appropriate). The structure of their mouth that they are predators surface. Arowana fish is a very powerful and predatory activities, We have the ability to launch out of the water to bite the bait.
Fish species are hatching dragon male mouth or something that is going to suck and the fertilized eggs in their mouths until the eggs hatching fry. Juveniles can still come back in the mouth brood away when in danger. In Asian Arowana and South America, males incubating duty, while in Australia Arowana, Females do this task. The process of going from village 4 to 8 weeks depending on species.
Topic classification arowana is quite common topics on forums aquarium, both domestic and foreign, however, we have 2 reason to again mention them here:
- First: gigas species in Africa (Hotter Otis niloticus) gigas and South America (Arapaima gigas) they are now classified as a separate – they gigas (Arapaimidae). So, when referring to them aro (Osteoglossidae), We will not list the mammoth fish as often as before. To distinguish, just remember that they Arapaimidaeno beardas aro.
- Monday: results of scientific research in 2003 Pouyaud of French scientists and colleagues on the dragon fish in Indonesia a new species isolated from single species is still known todayScleropages formosus. They include aros, great red dragon and metal dragon Borneo. We will update this information here.
We also detailed mapping of the natural distribution of the species in the world aro, hope that we will meet the public needs to know about arowana fish species you love this beautiful scene.
Asian Arowana fish is one of the leading landscape because reputation, value and natural beauty of our. Known as the shape and appearance similar to the dragon swimming in the legend, people believe that Arowana symbolizes luck, Prosperity, wealth and health. So, they are raised with the desire to bring positive effects fengshui. In addition, color of some species such as the Asian arowana red arowana and arowanas also given their best in general aro.
Asian Arowana are distributed in the countries in Southeast Asia and is closely related to arowana arowana Australia than South America. Pectoral and anal fins far back on their back but only Asian arowana 5 each side of the scales compared with 7 Asian arowana scales in Australia. Surprisingly, though very popular, but the scientific research related to Asian arowana is quite small, evidence that in a very long time all arowana Asia are grouped under a scientific nameScleropages formosus even though they have very different surface. The diversity of types of Arowana fish market is a testament to this. Research and colleagues Pouyaud (2003) isolated dragon fish in Indonesia into separate species of dragon blood (Scleropages doctor rotate), thanh long Borneo (Scleropages macrocephalus) great red dragon and metal (Scleropages aureus). The senior Kim dragon and dragon with Nami remains classified under the name DragonScleropages formosuseven though they may be distinct species.
Even, of each species can also have different lines. About the color, next dominant color scales beyond borders, color at the center of the so-called background. In each species, the distribution of the blue "blue-based", nền lục “green-based”, the yellow "gold-based", nền tím “purple-based”, even the silver, "silver-based" ... the color spread from center to border color scales is narrow scales thin rim "thin rim / frame", by reverse, clustered in the center background is scaly flakes thick border "thick rim / frame". In shape, lozenge shaped tail "diamond shape" and form fan-shaped tail "fan shape", the spoon shaped "spoon head" and the bullet-shaped forms "bullet head", wide body and short form, are long and slender body shape ... The crossing (cross breed) strains in a wild dragon species was quite common in the ornamental fish farm in Thailand, Malaysia, Singapore goes Indonesia. Hence, the scientific study of Asian arowana having a lot of trouble of having to rely on wild fish left very little capital.
Examples of these types of scales in species aros: 1- blue background, thin rim (blue-based, thin frame), 2- dark background, thick border (dark-based, thick frame), 3- especially as the background color almost disappears, all scales of government red.

Blood dragon (Scleropages doctor rotate)
Blood dragon (Scleropages doctor rotate).
Blood dragon (super red) Arowana is distributed in the upper Kapuas river and lake Sentarum, tỉnh Height Kalimantan, Đảo Borneo, Indonesia. Ho Sentarum is a collection of numerous small lakes eat together and with intricate system of canals and rivers flowing into the Kapuas. The area covered in mud and leaves derived from the wood to create wildlife habitat for this species early, black water and food sources are diverse positive impact on the color and shape of their. The diversity of the ecological environment can be created countless causes traits in species diverged aros. For example, some individuals with widebody, some other top spoon (spoon head), some are bright red or a dark red again. Research by scientists at the National University of Singapore in 2005 on 41 individual wild aros that the genetic differences between individuals can be quite large, this proves the existence of different strains aros. However, Scientists do not mention their external characteristics. The study further in the future will probably difficult because of the number of fish aro serious decline due to environmental change, mainly forest exploitation.
In fact, traders arowana red arowana previously divided into two categories based on their colors, That is "chili red" distributed in the south and "blood red" distributed in northern Lake Sentarum. Type "chili red" bright red, wide body and thick, while "blood red" color is dark red, long and slender body. "Chili red" are thick from head to tail in the "blood red" tapering towards the tail. Type "chili red" record with the "green-based", the spoon (spoon head) and diamond tail while the "blood red" color is dark red, nền sẫm “dark-based”, first bullet (bullet head) and fan-shaped tail.
Type "chili red" with red eyes and large while the "blood red" eyes are paler and smaller. Eyes "chili red" is so great that the outline of it "touches" to the head and lower jaw. The tail of the "blood red" tail fan-shaped diamond polished look of "red chili". This trait development when young fish can help us distinguish 2 fish easily.
Despite the differences, they both turn red when true adulthood. "Chili red" color to slower 1-2 in comparison with "blood red", but beautiful color with thin rim of scale "thin rim / frame". The process color both similar. Orange color is usually the time before fish turns red. Particularly with children to 8 old but still pale but suddenly the red color in a short time surprised farmers. The evaluation of a quality red arowana is sometimes difficult, requires players to effort and patience to discover its true potential.
"Chili red" and "blood red" is the name of the dragon fish, wildlife. Remember that wild fish are prohibited because they are buying and selling animals need to be protected. The fish farm fish often cross the two together to give the same blood dragon "super red", so in fact, pure blood line true dragon does not exist on the aquarium market whether individuals characterized by "chili red" or "blood red".
High quality red fish usually dark red in color and are surrounded from childhood. We also have striking colors and really dark back. These fish are also many beautiful iridescent body. This characteristic is evident when observing fish under natural light. When they reach 25-30 cm, gills and scales border with purple or red to brown, But if gold is not only operating at.
Theo Unoaquatics, out “blood red” và “chili red” There are two different types of dragon blood "red orange" and "red golden". Two types are orange and orange-red gold was not really like the first two. The author did not specify their origin, things that we can speculate that it is the individual hybrid. "Orange red" and "red golden" is often combined with “blood red” và “chili red” a "super red&qblood rednot by tandquality chili red Juveniles are very similar to genuine aros, but as adults can not achieve true blood red dragon. Indeed, If bloodlines are "treated" by the color quality is no way to distinguish so farmers should buy from reliable supplier, fish and chips incorporating full certificate.

Geographical distribution of natural aros (Scleropages doctor rotate): upper Kapuas River and Lake Sentarum, tỉnh Height Kalimantan. Geographical distribution of Borneo dragon (Scleropages macrocephalus): Melawi tributaries and Pinoh (DONG gray tail), West Kalimantan province and Barito River (dòng yellowtail), Trung Tinh Borneo.
Thanh long Borneo (Scleropages macrocephalus)
Borneo dragon fruit also known as known as "dragon Asian banks" (silver Asian arowana) because relatives and their bellies are white as silver dragon species South American banking. This species is itself larger than the normal species of dragon, small size, approximately 40 cm, specialpectoral fins short, not reaching ventral fin origin. Dragon Borneo consists of two lines is "greytail" or “Pinoh” (Pino is written as) Melawi distributed in rivers and Pinoh, two branches of the river downstream of the Kapuas. As the name, fins of these fish have colordark gray. The second line is "yellowtail" or "Kuning Banjar" is distributed in Barito River, Trung Tinh Borneo. Fins of these fish areyellow, gray rays.
Borneo adult dragon streakshorseshoe-shaped dark gray or blue violetvery nice on the scales, however, their size is relatively small compared with other Arowana.
Series "yellowtail" childhood fin pale yellow-orange should have called them "great red dragon" or "pink bar" . “Yellowtail” (HAY "Yellow train") often confused with "Banjar Red", a cross between a dragon fish Borneo with dragon blood that we discussed in the section "Personal hybridization". In fact, "Yellowtail" is a pure species. ("Banjar" refers to the city of Banjarmasin is located in Barito estuary).

Great red dragon Kim (Scleropages aureus)
Geographical distribution of species naturally great red dragon metal : Vung Pekanbaru, Riau Province and reserve Berbak, tỉnh Jambi.
This species is also known as "metal dragon Indonesia". They are distributed in Sumatra, Indonesia in the pond, small lakes along the Siak River, the flow through the Pekanbaru, Riau Province and along rivers Batanghari, flows through the reserve Berbak, tỉnh Jambi. This species is back and1/3 dorsal (tip) dark, the left dorsal, caudal and anal fins reddish or brownish. When I was young, Yellow colored fish slightly flushed but as an adult, which was about the size of 28-34 cm, colors of us will grow up and fish with dark yellow.
Like arowanas context, This species is divided into several categories, including "green-based", "Blue-based" and "gold-based" depending on the color scales in mind. However, great red dragon needle is ranked lower because they are not bright yellow color of the background metal dragon, on the other hand usually only develop color scales to Wednesday when adult fish. The fish are better quality known as "high-back" (highback) great red dragon metal colored scales grow up to Thursday but never exceeded backs, color on the gills and scales well defined borders even young fish, approximately 15 cm. Their fins have dark red.
Compared with arowanas context, great red dragon metal have good stamina, small head, Elongated and more aggressive every child should usually be kept separate. The price of the metal is relatively great red dragon "soft" than metal dragon blood dragon and set up too many people choose to raise.
Great red dragon Kim (Scleropages aureus) normal color scales do not exceed Wednesday.
"High waist" great red dragon metallic colored scales grow up to Thursday.
Dragon (Scleropages formosus)
This Arowana is worth less, but the most popular among the Asian Arowana. Dragon species widely distributed including the island of Borneo and Sumatra in Indonesia, Malaysia, Southern Thailand, Cambodia and Southern Vietnam. Dragon fruit has a maximum size of about 60 cm, dark blue back, silvery or bluish body, violet blue fin(Main characteristics to distinguish species of dragon Borneo), brown-red rays. In mature individuals, around the eyes turn blue pearl. We usually have the form of bullet-shaped. Please note that both species of Borneo with dragon fruit is usually (Scleropages formosus) Borneo and the dragon (Scleropages macrocephalus).

The senior Kim dragon
The senior Kim dragon (crossback golden) also known as "metal dragon Malaysia", This is a beautiful two dragon fish and most expensive fish market (other species are aros). Unfortunately, phase of research scientists and colleagues in Pouyaud 2003 This ignores the reason fish do not have enough samples to study. So, This breed is still being put together with dragon in the name of scienceScleropages formosus, however, based on surface characteristics, they are very similar to the great red dragon metal species, speculate that this helps both closely related to each other. The senior Kim dragon distributed in the state of Pahang and Bukit Merah lake, bang Perak, Malaysia (documents listed may also add Johor and Trengganu). They have big heads and bodies are relatively short compared to other similar Asian arowana. Compared with metallic pink dragon great, arowanas have a bright yellow background and always developing scales to Thursday. General, Given a quality arowanas have color scales, bearing cap and the area around the eyes morning and are, color development up to the back, especially when the fish near the dorsal fin is small (under 15 cm).

Kim dragon too set is divided into several categories including "blue-based", “purple-based”, “green-base”, "Gold-based" and "silver-base" depending on the color scales in mind. The type of "Blue-based" and "purple-based" is the same as blue or purple depending on the angle, when young fish are usually dark. The dark green and light spread on the scales and gills grow up to be very beautiful. Với loại này, blue scales usually spread attention as yellow flakes on the rim narrows (thin-frame). Type "gold-based" as children often have pale yellow, color developed on the back of them earlier than others. This class looks very attractive because the adult body like yellow 24K gold ingots mobile! Với loại này, dark yellow scales at the center usually shrink as yellow flakes on the rim width (tWith this kind
Kim context of the golden dragon too "gold-based" and the thick flakes “thick frame”.
Indeed, sometimes very difficult to distinguish arowanas of any kind given above because today people crossing (cross breed) with different types. The crossing also helped create the context of the particular metal dragon as "platinum" and "royal blue". These are pretty new so the price is very high and often sold through high-end markets such as Japan and Taiwan.
General, arowanas context is one of the most expensive arowana just because they are rare and little reproduction than other varieties aro. For reference, we have listed arowanas rankings given by William Goh (http://dragonfish.com):
- Economy Class: loại “gold-based”, "Blue-based" pale and different types of background. Color development on 50% secondary scales 5. Pale colors than the Class A and AA. Price from 2.000-2.800 Djo-la / 1 with 14-19 cm.
- Class A: Category "emerald blue-based" instant background turquoise, kind of "blue-based" Bukit Merah lake origin and "gold-based". Color development on 50% secondary scales 5. Fish under 8 months of age and size below 20 cm. The most important point is that the individual must have a "spoon head" and being pursed lips. Price from 3.000-3.500 Djo-la / 1 with 14-19 cmcm
- Class AA: Category "emerald blue-based" instant background of emerald green and "blue-based" originating from Bukit Merah Lake. Color development scales up the whole thing 5 and a little "continent" appeared in the dorsal root. Fish under 8 months of age and size below 20 cm. The most important point is that the individual must have a "spoon head" and being pursed lips. Prices 3.800 Djo-la / 1 with 14-19 cm.cm
- Class AAA: rare fish. Color must develop scales up to second 6 on the back and a little "continent" appeared in the dorsal root. Fish under 8 months of age and size below 20 cm. The most important point is that the individual must have a "spoon head" and are a perfect mouth. Prices 10.000 Djo-la / 1 with 14-19 cm.cm
- Class AAA: fish are extremely rare "gold head", "Full gold" và "platium". Color must develop scales up to second 6 on the back and a little "continent" appeared in the dorsal root. Fish under 8 months of age and size below 20 cm. Type "gold head" with the yellow markings on the head, of "full gold" yellow body is kind of "platinum" silver body. Special Price High.
Note: Kim Long Malaysia there are individuals that color is not up to the scales Thursday (referred to as the Malaysian Golden) or color scales up to Thursday but did not come back (known as Malaysian Golden Highback). On the same line and color quality, they are similar to the class that the given color back to the first and. According habits, people still referred to all three is "arowanas context". Need to distinguish them from metal dragon Indonesia, including metallic pink dragon great (Redtail Golden) high and mighty red dragon back metal (Highback Redtail Golden).

Asian dragon fruit including Nami (Malaysia) Batik and dragon (Burma). Year 2012, ichthyologist Tyson Roberts has identified as a dragon Batik Arowana separate scientific nameScleropages inscriptus. It is likely, Nami dragon also identified a new species of this.
When I was little, Asian dragon colored dragon often similar, but as an adult, on gill, scales and pectoral fins appear iridescent patterns look very attractive, red ankle. Geographical distribution of natural fruit Nami Muda dam, bang Kedah (northwestern Malaysia). Natural geographical distribution of Batik dragon in provinces Taninthayi, southern Burma. These fish have similar pattern was also found in the province of Satun, southern Thailand.
Now, Asian dragon appears not mass marketed fish because fish can trade wild prohibited; however, fish farms in Malaysia are conducting their breeding. The generation of offspring born in captivity will be fitted with chips and export permits. Hopefully in the near future, Arowana lovers around the world can own this special breed of dragon fruit.

Because the cause of economic and technical, it was a hybrid of the Asian Arowana together. The following are common types of hybrid fish on fish market:
- "Banjar red" or dragon blood type 2 a hybrid between red arowana fish for "yellowtail" or dragon. This fish has fins and body blush.
- "Tong Yang" (SABF), “Red splendour” (Qian Hu), “Crossback splendour” (OTF), “Rose Gold” (DFI), is a hybrid between red arowana fish for arowanas context, they often have varying degrees of orange. "Red Splendour" is a competition section in the annual exhibition aro held by Qian Hu.
Australian Arowana generally smaller scales compared to Asian arowana. Each side of the Australian continent aro 7 scales compared with 5 scales in Asian arowana. Australian Arowana lateral from 32-35 scales than from 21-25 Asian arowana scales in. Another feature that identifies pairs of Australian bearded dragon fish is not pointing straight ahead as the Asian arowana that curl down like goatee. Unlike the Asian Arowana and South America, Australian Arowana the duty shut and hatch.
Australian Arowana species identified are known to be territorial and aggressive fish amongst the dragons, especially speciesScleropages leichardti. We need to pay attention to these factors when kept together with other Australian Arowana and other fish with, best to keep them separate. Arowana Australia is not in the list of animals in need of protection. Information and pictures on them are often found on websites introduce fishing in Australia! Australian Arowana Price from 20-200 dollar / 1 depending on the size and color.
Pearl Dragon (Scleropages jardinii)
Pearl Dragon (pearl arowana) also known under other names such as Gulf Saratoga Barramundi, or Northern Spotted. This species in the rivers and flows down to the Gulf of Carpentaria in the Northern Territory and Queensland, Australia. It also noted the appearance of them in the southernmost part of the island of New Guinea. They are suitable for water environment in the river upstream.
The maximum size of the dragon pearl 90 cm, but the fish kept in aquariums usually only about 60 cm. In juvenile fin usually pink, but pink when mature fish will lose, gills appear red stripes patterned copper. Back fish is bluish gray or brown, golden bronze body, color appears on the outer edges of the scales, the yellow dots on the scales, orange or red and are close together formingalternating stripes. Fin black with large orange spots or red. Dragon Pearl commonly circulating in the aquarium trade under the name “metal dragon Australia”, especially the red-brown color is very rare and expensive is called “red dragon Australia”.
Fish usually spawn the month 10, rainy season that started in Australia. Each time the female lays 50-100 eggs, the female incubates the eggs for about 5 week.

The Red Dragon (Scleropages leichardti)
The Red Dragon (spotted arowana) also known by other names like Spotted Barramundi or Southern Saratoga. This species is distributed in the river basin Dawson / Fitzroy, northeastern Queensland (of the). Unlike the dragon pearl, the red dragon fancy turbid water in ponds and swamps with aquatic plants growing on the surface.
The maximum size of the red dragon 90 cm. Gill no pattern. Back fish is bluish gray or brown, Pale green body, the scales from 1-3 red-orange dot in the center so the overall look will see the fish bodysingle red spotinstead of alternating stripes as the dragon pearl. Fins have black rims with red dots orange. The back is flat pink than the dragon pearl fruit.
Red dragon reproduction of the month 8 and 9 annual. The number of eggs and the incubation period is similar to the species of pearl dragon. This species is less common in the aquarium trade than their cousin the dragon pearl.

South American Arowana
South American Arowana Arowana distinguished Asia and Australia in the fin. In South American Arowana, The dorsal and anal fins starting the overlapping between the body and caudal fin to create a sense of the continuum we, small pectoral fins and tail from body. While Arowana Asia and Australia, dorsal and anal fins short and recede back, large pectoral fins and tail from body.
Life of South American Arowana can reach 20 year. In addition to the natural environment, dragon fish live in rivers and swamps. When water withdrawal, we can gather in packs to hunt prey. When the water, aro scattered everywhere. We're all kind of food floating in the water as small fish, insects, frogs, even the birds, reptiles and small animals, generally all that fits their mouth!
Banks dragon (Osteoglossum bicirrhosum)
Fish dragon banking (silver arowana) distributed in the Amazon basin, sông Rupununi (Guyana) VA Oyapock (French Guyana), South America. This species has a maximum size 1.2 meters, scales to, mandible optimism, body looks like a knife and not elected on the list of protected species must. When I was little, The fish themselves are iridescent blue markings and orange, head and fins with black spots, fins pink border. As an adult, turns silvery fish. Males have long pointed anal fin than females.
Fish dragon banking is relatively cheap prices, 20-25 dollars a fish, they are most commonly grown dragon. However, Recent literature in Peru (Moreau & Coomes, 2006) shows that the arowana exploitation exhausted ongoing, Besides locals harvesting immature fruit by banks… father beheaded fish to prevent them swallowing the stomach. The temporary limited hunting of local fish during spawning showed no effect. Now, one bank is campaigning to visit the list of fish species in need of protection similar to Asian Arowana and gigasArapaima gigas. If this is true, the price of dragon fish in the future banks will likely increase.

Black Dragon (Osteoglossum ferreirai)
Black dragon fish (black arowana) distributed in the Negro River basin (of the), a tributary of the Amazon River. Black dragon fish shaped like fish fins and body dragon budget black when immature fish. When adult fish, body grayed, bluish colored fins should have known they were “blue arowana”. Black dragon fish slightly smaller banks dragon fish, we have a maximum size 1 meters. Black dragon fish have similar rates banks dragon fish, but the fish are small bluefin was sold for a high price, about 500 Djo-la / 1 with 25 cm.
Black Dragon (Osteoglossum ferreirai).
The dark blue dragon fin is relatively small when it was assigned to the new name “blue arowana” (Osteoglossum cf. ferreirai) for commercial purposes. Because there is no scientific evidence to support this should in fact they are only black dragon fish (Osteoglossum ferreirai) only (sourcewww.aquarist-classifieds.co.uk).
