However, when cared for properly in captivity, these magnificent creatures can extend their lifespan even further. Originating from regions with slow-moving waters, such as wetlands, forested swamps, and blackwater rivers, Arowanas have a strong preference for warm water. To recreate their ideal conditions in an aquarium, it’s crucial to maintain a water temperature between 75 and 85 degrees Fahrenheit (24-29 degrees Celsius).

Due to their substantial growth, it’s important to provide ample space for your Arowana fish in their tank. While a 60-gallon tank may initially suffice for young Arowanas, they will soon outgrow it. To accommodate their size when they reach full maturity, consider investing in a spacious 250-gallon tank.

Arowana fish tend to be reclusive and appreciate hiding places and shelter in their tank. You can create hiding spots with plants or rocks. Some aquarists opt for dark backgrounds in their tanks to provide Arowanas with a sense of security. Additionally, maintaining effective filtration in the tank is essential, as these fish produce a substantial amount of waste. To keep the water quality optimal, regular water changes and frequent filter cleaning are a must.

To ensure the well-being of your Arowana fish, it’s essential to maintain specific water parameters. Aim for a pH range between 6.5 and 7.5 and a water hardness of 10-20DH

Aquatic Plants & Decoration

Lava rocks are a fantastic choice for stones since they can contain microorganisms and aid with aquarium filtration. Additionally, the aquarium can be embellished with sizable pieces of driftwood. However, Arowana enthusiasts frequently choose to house these fish in a huge, empty tank with a dark background.

To keep up with this growth rate, it is advisable to feed young Arowanas twice a day with top-notch food. As they mature and their growth rate slows down, along with a decrease in metabolism, their appetite naturally diminishes, and they will accept smaller portions of food. Subsequently, it is sufficient to feed sub-adult to adult Arowanas once a day as long as they continue to show an interest in food.

Furthermore, it is worth noting that keeping the shell or exoskeleton intact on shrimp and prawns has been known to enhance the red pigmentation in Arowana fish.

As juveniles, Arowana fish are readily receptive to small live fish and various tiny insects like worms, roaches, and crickets.

Although it can be challenging, some Arowanas may eventually accept processed foods like pellets.
