Arowana is one of the most expensive fish to buy, as well as feed. Interestingly enough, this fish is considered a good luck charm in some cultures. Buying an arowana can be quite difficult for there are a lot of excellent breeds to choose from. Once you have chosen an arowana, care for each breed will vary so ask your local pet store on how to feed your fish properly.
A tank size of 100 gallons is ideal for each fish. The more arowanas you have, the more the size of the tank should be increased. If you plan to buy several arowanas, they must be introduced in the tank all at once. This fish is highly dominant, and territorial battles will ensue if the fish is introduced one after the other. As much as possible, you must cycle your tank before you bring home your arowana. A new tank with an incomplete cycle will cause stress to your arowana. This will cause the fish not to eat for several days, sometimes up to a week or more depending on the stress level of your fish. Take care to keep the water running inside the tank.
Water changes should not be so drastic. A 10% water change every two or three days would be ideal. If you see that the water in the tank is gets cloudy real fast, adjust your water change accordingly. Remember to regulate the amount of water change for too much changing can disrupt the nitrogen balance of your tank. Filtration is important, so see if you can have a filtration system that can both filter your tank as well as aerate the water. Lack of oxygen and water flow can cause some serious disease in an arowana, particularly over-turned gills.
Feeding is not particularly difficult. The only problem is having enough supply for your arowana can be a voracious eater. Small arowanas need small fish such guppies. If that’s too expensive, a prepared frozen meal of shrim, beef hearts, and enriched flaked food will be good for your fish.
Tank decorations may or may not be necessary. Problem with tank decorations is that they can be destroyed when your arowana gets startled. Sharp gravel can damage the snout of your arowana. Some have bare tanks for their fish, but others find it that a set-up tank calms down an arowana. It’s entirely up to you if you wish to decorate your tank or not. With proper care, your arowana can live up to more than 20 years.
Remember to introduce your arowana slowly into its environment. And remember that they get very big quickly. Purchasing a small arowana for your 30 gallon fish tank is not a good idea. You should already have an established tank of at least 100 gallons. 100 Gallons should be the bare minimum. 150 and above is the smarter choice. Arowanas are amazing fish and you will love keeping them. You just need to make sure you do it right. Good luck with your arowana.
