Types of Arowanas

There are many types of arowanas, all of them have their own unique beauty.


Asian Arowanas

Red Arowana 'Hong Long'

Crossback Arowana aka XB (not CB cos CB stands for something rude) 'Guo Bei Long'

Red-Tail Gold Arowana aka RTG 'Hong Wei Jin Long'

Yellow Tail Arowana 'Wang Wei Long'

Green Arowana 'Ching Long'


Hybrid Asian arowanas

Tong Yan (Red X Crossback)

Grade 1.5 red (Red X Green) - Note that the certificate of 1.5 red aros states grade 2 because it is impossible to differentiate a grade 1.5 from a grade 2 for young specimens. All are tagged lower at grade 2 to prevent people feeling cheated if their grade 1.5 turn out to be grade 2. If all are tagged lower, the only thing that can happen is some people get a surprise that their grade 2 grows up to be 1.5)

1.5 red still have reddish/brownish tails, but the scale shine is lower and green horseshoe markings are prominent (due to green genes) on the scales. The lips is brownish.

Grade 2 red (Yellow x Green)

2 red have orangish/yellowish tails withl prominent green horseshoe markings on the scales. Lips are colourless.


South America Arowanas

Arapaima aka Giant Dragon 'Ju Long'
This is the biggest arowana, only suitable for huge water bodies. It is only a matter of time before it outgrows any home tanks. Despite some rumours, they are completely harmless to humans.


Silver Arowana 'Yin Long'

This is the most common arowana in fish shops because of the large number of offsprings they produce (also leading to lower price). They have fully silverish bodies with little bit of pink on the fins.

Black Arowana 'Hei Long'

They are black when young, leading to their name.


Australia Arowana

Pearl Arowana aka Jardini 'Zhen Zu Long'

Red spotted pearl aka leichardi 'Hong Dia Zhen Zu Long'

Australian arowanas are more aggressive than asian arowanas and swim faster due to their more hydro-dynamic body shapes. They are also naturally less broad and more streamlined. Their scales are smaller.


African Arowana

African Arowana 'Fei Zhou Long'

Their body look like arowana but their head looks like the head of the climbing perch.


Arowana Care

The main thing about arowana is they can grow big compared to normal aquarium fish. If you do not have a big tank, then you will not be able to see them swim in their natural beauty and grace. A minimum tank size of 4'x2' is a requirement, a 5'x2.5' is ok. As large as possible is best.

Arowanas will eat any live food that will fit into its mouth. Note: Less than 1% of all Asian arowanas will take pellets.

Arowanas are rumoured to breed in mud ponds only. That is however a rumour. The main reason that they don't breed in fish tanks is because of the food. They need plenty of live food to get into the mood, a mud pond allows that because insects like centipedes,crickets,grasshoppers and many other creey crawlies fall into it all the time like a constant food supply. Less arowanas breed in concrete ponds than mud ponds for the same reason. Concrete ponds have a walking edge at the sides of the ponds so less insects fall in. Mud ponds have grass and vegetation up to the very edges of the ponds so more insects fall in.


Arowana community tanks (Aro com)

To set up an aro com tankis a difficult task because if done wrongly you with get dead arowanas!

Rules to setting up aro com tank

1. All arowanas has to be of the same size. This rule cannot be bended.

2. Big tank is necessary. Since it is impossible to create hiding places for them, in a confrontation, the weaker aro needs to have space to evade attacks. They don't need a football field of space to outrun one another since arowanas don't chase for long distances (They're not like cats!) . But they need the space to perform 'sidesteps', during mini confrontations.

3. The more fish the better. When in big numbers, aggression is spreaded out and a fish that loses a confrontation can 'disappear' behind the other fishes with a quick turning.

4. All the arowanas must be introduced to the tank at the same time.
