General Knowledge about Arowana

Description:

This family of fishes, you can find that the head is bony and the elongate body is covered by heavy and large scales, with a mosaic pattern of canals. The dorsal and the anal fins are long based and have soft rays, the pectoral and ventral fins are tiny. The name 'bony tongues' came from a toothed bone on the floor of the mouth, the 'tongue', equipped with teeth that bite against teeth on the roof of the mouth.

Habitat/Care:

In the wild, the Arowanas prefers to stay near riverbanks with shallow waters, typically as deep as 5 feet, and in shaded areas. In such an environment, insects, which are their main source of food, are plentiful.

Mixing with other fishes:

Arowanas are highly territorial and will not tolerate another Arowana in a small tank. In a large open pond, however, several Arowanas can be kept safely together. Wikipedia recommends that 5-6 Arowanas should be kept together in a tank instead of 2-3 as when in a group, their aggressiveness tends to be subdued.

Do take note that small fish that can fit into their mouth will become their meal.
Medium to Large bottom feeders are good tank mates for the Arowana. The Arowana will leave these bottom feeders alone. Other peaceful large fish can be considered to be placed together with Arowana. Take care not to include fin-nippers with the Arowana.


Diet:

Arowana will generally not eat from the bottom of the tank. They prefer live food or at the very least floating food. At this point, keeping your Arowana with a suitable bottom feeder may be a good idea.

Some foods help to promote a good color in your fish, such as prawns and shrimps contain cerotine which helps bring out the red and gold colors of the Arowana. It is recommended however to maintain a varied and balanced diet for any Arowana.

These foods can include: worms, crickets, grasshoppers, locus, fly, small frogs, small fish (limited quantities) and shrimps with shells. Some Arowana may take floating fish food.


Feeding patterns affect both size and color of your Arowana. Over feeding can make your fish grow faster however this may adversely affect both color and long term health of the fish. Since the size, color and health of your fish are all very important, you are advised not to regularly overfeed any Arowana.
