Preparing For An Aquarium

Proper preparation must, and we have to emphasize must, take place prior to introducing your
new Arowana to its new environment. There are many different methods of setting up a
successful aquarium for Arowana but the method we use, that provides the most suitable
environment, will be outlined further in this article. Arowana are expensive, so it is crucial to
have their environment set up prior to their arrival.


Things You’ll Need

Large 100-gallon aquarium with lid (Arowana can grow up to 3 feet)
Submersible aquarium heater (with guard)
Carbon filter
Reverse osmosis system
PH tester (to test the acidity of the water)
Ketapang leaves (Optional, but better for the fish)
Aquarium thermometer (preferably digital for accurate readings)
Aquarium filtration system


Setting Up The Aquarium

Place the empty aquarium in desired location. The location should not be in direct sunlight. The
aquarium should be placed on a stand for display and protective purposes. Please make sure
your stand is made for your tank, as it will have to withstand a very heavy weight.
Fill the aquarium with water until it reaches 2 inches from the top. Arowana love to swim just
below the surface of the water, so there needs to be room left for this.
Use a carbon filter to get rid of the chlorine that may exist in the water.
Once chlorine levels are non-existent install and use the reverse osmosis system, which gets rid
of minerals in order to make the water softer. Arowana thrive well in soft water. Most tap water is
hard which is why it has to be processed.
Test the pH level of the water once the reverse osmosis process has finished. We tend to keep
the pH level between 6.5 and 7.3. Use the dried Katapang leaves to sustain the pH at these
levels. Katapang leaves won’t harm the environment for the Arowana. They are in fact healthy for
Arowana. Now it’s time to check the temperature of the water, which should be between 76 and
80 degrees. Install the filtration system according to specific instructions provided on product.
Once the filtration is completely matured (which can take several weeks) and you have checked
that all the parameters are holding steady over a 7 day period, then you are ready to carefully flo
at/transfer the fish into its new environment. Make sure to check the pH and temperature
regularly and clean the tank once a week leaving 70% of the water in the tank with the Arowana
to prevent discomfort for your new fish. That’s it. You have successfully created an environment
that is best for Arowana to live in. Now all that’s left is to feed it, sit back and watch it grow


Feeding Your Arowana

Arowana are carnivorous, which justifies why they are aggressive in nature. They pretty much eat
anything. Brine shrimp and small fish are decent items to include on their menu. Juvenile
Arowana eat more since they are in the development phase and should be fed three times a day,
at equal intervals. Medium size Arowana only need to be fed twice a day and adult Arowana
should be fed at least once every two days. With feeding comes waste and the waste will typically
change the PH of the water. The pH levels should be checked on a regular basis to prevent
irregular levels.
Remember to remove at least 30% of the water weekly, and replace with fresh water. For smaller
tanks remove about 20% of the water making sure to replace this as well. Replace the lid on the
tank after every feeding and cleaning as Arowana are renowned “Jumpers”, so please ensure the
lid is always firmly in place.
