First introduced in 1912, ..."The Arowana gives us a view of our ancient prehistoric world, the world during the Jurassic age. The Arowana is one of only a few living examples of this group."The Arowana or Silver Arowana is related to early primitive fishes and is sometimes called the "Bony-tongued Fish".
One of the most interesting fish, the Silver Arowana gets rather large. A 47 inch specimen, although rare, will need an aquarium of at least 100 gallons just to turn around! Though they can be kept together when small, larger specimens are best kept singly or with other species of larger fish. They are a predator and will eat small fish. But on a positive note, they can become quite tame and take food from your fingers. These fish are excellent jumpers so make sure the top of the aquarium is covered. The Arowana will prefer an aquarium with a fine gravel bottom planted loosely with hardy plants and open areas on the top to swim. For more Information on keeping this fish see:

The Arowana, also called the Silver Arowana or Bony-tongued Fish, was described by Cuvier in 1829. They are found in the Amazon Flood plains where they feed at the surface, mostly on fish but also on insects such as waterfleas and insect larvae.
Status:
The species is not listed on the IUCN Red List.
Description:
The Silver Arowana is a long fish with lithe
fluid swimming motion that makes it seems almost snakelike. It has large
opalescent scales that reflect blue, red, and green highlights as the
fish grows older. The mouth is at the top of the body and opens in three
pieces.
Size - Weight:
These fish get up to 47 inches (117 cm). Usually they are
much smaller in aquariums, with 24 to 30 inches being a good sized Arowana.
Care and feeding:
Since they are carnivores,
the Silver Arowana will generally eat all kinds of live foods.
Sometimes they will accept large flakes or pellets which is desirable in
order to give them a balanced nutrition.
Water Region: Top, Middle, Bottom:
These fish will swim in the top of the aquarium.
Acceptable Water Conditions:
Hardness: 8-12° dGH
Ph: 6.5 to 7.0
Temp: (75-86° F) 24-30° C
Social Behaviors:
They are generally not a good community fish. Only small
specimens can be kept together and with other fish. As they get older
their size and the fact that they eat other fish makes them unsuitable
for any but the largest of tankmates.
Sexual Differences:
The male is more slender and has a longer anal fin.
Breeding/Reproduction:
Water parameters for breeding the Arowana
or Bony-tongued Fish are the same as for general maintenance above.
Feed large amounts of live food to induce spawning. The eggs are up to 1/2 inch in diameter. The male will brood them in his mouth. After 50-60 days the eggs will develop and produce fry which have and obvious eggsak. They are 3-4 inches long before this is gone and they will feed entirely on their own.
Availability:
The Arowana or Silver Arowana is available from time to time.

| Silver arowana grow very quickly, a 10" silver will be 24" within 12 to 18 months. A 3' x 1' x 1' tank is way too small, it is best to wait and provide a proper sized tank.

| I heard about a golden arowana in our town on Balinsasayaw Lake in Sibulan Negros Oriental Philippines. I heard it from my friends that there was a golden arowana in that lake, the arowana was 1 and 1 half feet long. A fisherman caught the arowana in maybe 1995.

| I am going to purchase a silver arowana 8-10 inches within a week. I had been keeping freshwater aquariums for 5-6 months. My current aquarium size is 3*1*1.

| My brother and I are owners of a 20 inch silver arowana,16 inch albino oscar, 19 inch rare albino(white)clown knife, 25 inch red bellied pacus, and an 18 inch pleco. They are all housed in a custom 1000 gallon aquarium. It has an amazon river theme. All these fish are a beautiful addition to any large aquarium. Definitely not recommended for a beginner. Its very fun to watch them grapple 3-6 inch feeder fish. These fish are very costly for they consume 5-6 hundred comets(adult gold fish) a week. The tank is filtered by custom filter which filters 1,200 gallons an hour. A setup like this will roughly cost anyone a good 6,000-8,000 dollars. But it is worth every dollar.

| I'm an owner of a custom 475 gallon aquarium dimensions are 72x36x43. It is used to house a five inch Malaysian Green Crossback Arowana that was recntly purchased two months ago. This is my second arowana that I currently own my first was a Asian Red Arowana from Thailand. The Asian Red had an array of a color that was extremely attractive to the human eye. I sold him to a man that lived in east Texas for $33,000 and was the most profit that I ever made on a fish that I sold. The paramaters of the water must be Ph 7.0, Ammonia 0, Nitrite 0, and Nitrate 0. Temp keep at 80 F. The aquarium has an overflow box in the center which is connected to a 150 gallon sump in the bottom that houses several bio media sections which will fliter out all impurities. Diet consist of fresh bay shrimp, pellets, and on occasion pinkies. Water changes are done bi-weekly with an automated R/O system connected in the sump itself.
If you like any Arowana of any species of this kind I would recommend starting out with the silver and working your way up. 2005-07-15 |
