Asian Arowana:
Is the most famous and expensive Arowana in the world . They are currently Red , Gold , Green and a mixture of both types of Asian Arowana . All the Asian Arowana is protected species because they are near extinct except for Yellow-Tail and Green Arowana .

Sci. Name : Scleropages Formosus 
Size : Maximum up to 36 inches 
Temperature Range : 75 - 85 F 
Distribution : Southeast Asia (S. Thailand, S. Vietnam, Malay Peninsula, Sumatra and Indonesia)

Red Arowana is found in Kalimantan and Sumatra of Indonesia. They can be divided into 1st grade red and 2nd grade red. 1st grade red can have different intensity of color ranging from yellow to orange to red to blood-red and chili-red. The higher intensity red is more desirable and often demand very high price. It is often difficult to differentiate 1st grade red from 2nd grade red when the fish is young.

Young 1st grade red's tail and anac fin have intense red color and their scales are shiny gold in color with some green at the base. Young 2nd grade red has orange fins and the scales color are no obvious and often whitish silver. When the fish grows, in 1st grade red, the color of the fins remains red, their scales and the gill cover will develop its color. There type of color it will developed into depends on which type of 1st grade red you have. On the other hand, the adult 2nd grade red will only have pinkish or orange colored fins, their scales and gill color will only developed pink or orange color.


Is by far the most beautiful and famous Arowana among all the other Arowana . The scales and fins are totally red in color and it is very expensive . There are also ruby-red and Chili-red Arowana .The red Arowana is very popular among the Chinese and is believed to bring prosperity and wealth to the owner. It is considered an endangered and protected species . There are 1st Grade and 1 1/2 Grade Red Arowana

The Red Arowana is arguably the most prized aquarium fish in the world. It is probably the most expensive fish in the world on the basis of the highest dollar amount ever paid for a single fish. Its price variables include size, condition of body parts and overall body shape, color, and wealth with motivation on the part of the buyer. A large Red Arowana will usually command tens of thousands of dollars and in some cases hundreds of thousands."

There are basically four different varieties of Red Arowanas namely Blood Red, Chili Red, Orange Red and the Golden Red. In recent years, Chili Red, Blood Red, Orange Red and Golden Red are grouped together and termed Super Red or `First Grade Red'. It has made the termed `Super Red' inferior since Orange Red and Golden Red do not bear the qualities of the former two and they have only comparatively colors appear either in orange or golden orange. The usage of terms has indeed changed over the years and the term Super Red is now becoming more commonly used among breeders when naming their red arowanas.

Gold Arowana
Is also one of the expensive Arowanas around and it is sought after by many Chinese businessman .This Arowana is believed to bring good wealth and prosperity to the owner because of its beautiful gold color which look like gold bar .

Name: Scleropages formosus

It's rewarding yet a very risky to own this kind of species. Considering that they are endangered and very expensive, to which some require papers for authentication, it's very challenging. I should say it's an investment, especially for some businessmen who love to own this one, because of their mythical beliefs. It's said that it can bring good luck and fortune because of its gold color, symbolizing the dragon. This fish is famous in Asian countries. Some stores make it as their front display to attract costumers and fortune. 

They cannot be bred in aquarium and can live alone. If you're planning to add some other species be sure to choose them carefully. I would suggest those that swim in the bottom like rays, or some fast moving fish.To ensure the beauty of this fish, you shouldn't put anything in the tank to avoid scale injury, because they are soft. 

Generally, the Red Tail Golden is the tougher of the two Golden types and can  grow bigger in size but is the more aggressive of the two. Thus, it is more difficult to raise them together in one single huge tank (preferably 8 - 9 fishes) as compared to the Malaysia Gold. It is also protected by the CITES, even thought it is in more abundance in the wild. Apart from that, its tail, finnage and lip color are very identical between these two types of golden varieties.

Red-Tail Arowana (Red Tail Golden): 
Is a common Asian Arowana in Singapore . Its scales slightly become gold as it matures and the fins are red in color . When the Red-Tail Gold Arowana is young , it look the same as the 1 1/2 Grade Red Arowana since both have red fins and tails . But as the Arowana matured , a Red-Tail Arowana will have red-colored fins and tails with shiny body scales . 

Commonly known as Red Tail Golden (RTG) or Indonesia Golden Arowana, they are classified under the golden varieties as with the Malaysian Golden or Cross Back Golden. It is found in Pekan Baru of Indonesia. The prices for the Red Tail Golden are more affordable as compared to the Cross Back Golden. The reasons for this is that this fish seldom attain 24K gold as the Cross-Back Golden would and the golden color of Red Tail Golden Arowanas will never cross over its back even when the fish is matured or fully grown. It is thus not as great looking as compared to one that is “whole piece gold". Most Red Tail Golden arowanas will have its golden color reaching the fourth row of the scales and the better ones will have it's golden color reaching the fifth row. And, just like the Cross Back Golden varieties, Red Tail Golden also have different scales base color in either blue, green and gold. Young RTGs will have a duller overall color as compared to Cross Back Golden which is neatly defined, shiny and glittering with scales reaches the fifth row.

Crossback Golden Arowana:
This is found in Malaysia and sometime called Malayan Bony tongue. It has golden scales to the fourth column and pinkish abdomen when young. When the fish grow up, the golden scales will escalate to the fifth column hence cross-back) and the pink abdomen disappear. The scales may have different base color such as gold, silver or blue. Blue being the rarest. The scales can also divided into thin or thick golden frame. Thin frame scales blue base cross back gold are one of the most demanded arowana and hence often the most expensive.
