An Arowana hobbyist should definitely have an Asian Arowana in his tank. Scleropages formosus is found in Southeast Asia. This endangered Arowana species thrives on slow moving rivers. Purchasing and transporting them outside of Asia requires license. This species is noted for its color and large scales. The scales are netted or banded with colors. The long pectoral and dorsal fins of this species makes it more beautiful to look at. Myths have surrounded this Arowana. In fact, it is referred to as Dragon Fish because of its similarity in some ways to the Chinese Dragon.
There are many varieties of the Asian Arowana. There is the Green Arowana from Indonesia; the Banjar Red from Banjar Nasin; the Red Tail Golden from Sumatra; the Golden Crossback Arowana from Malaysia; Red Grade 1 from Kalimantan and the Tong Yang, which is a crossbreed between Golden Crossback and Red Grade 1.
Keep your Asian Arowanas happy by giving them enough space to swim in. The tank size for one is ideally 4 x 2 x 2 feet AT A MINIMUM. Should you decide to keep more, you should get a larger tank. This species particularly likes soft and slightly acidic water with pH maintained at 6.4 to 6.8 and water hardiness at KH2 to KH20. An abrupt temperature change is not healthy for your fish. Appropriate temperature will give your fishes more coloration. The tank must be properly filtered. Knowing that Arowanas are carnivorous, they tend to release more waste. Filtration should depend on the size of your tank. You can always use biological filters if your tank is not that big. Tank water should be changed at 10% to 20% once or twice a week. Arowanas cannot tolerate unexpected changes in their water.
Like any other Arowana species, this Arowana has preference towards live fresh food, which is live food. This fish is a surface feeder; you may feed them with floating food. They can be fed with mealworms, shrimps, small fishes, and even moth larvaes. Don’t feed them with the same thing each time. Provide variety for healthy nutrition. For better color development though, it is best that you feed them with live food feeding on food rich in ceratanoids. This will enhance their red and gold color. Don’t zealously feed your Arowanas, they might end up overfed, which is not healthy at all. An adult Asian Arowana may be fed every other day.
If you take good care of your Asian Arowana, they could live up to 20 years, and for those who believe in Feng Shui or Vastu, will bring you health, wealth and prosperity.Tags: gold color, banjar red, Tank Maintainance, color development, large scales
