Platinum Arowana Lifaspan

The Platinum Arowana is a long-lived fish, with a life expectancy that can extend to over 20 years with proper care and under optimal conditions. Some have even been known to live up to 25 years or more.

Their longevity is one of the many aspects that make them highly sought after by aquarium enthusiasts. However, it’s important to note that this long lifespan is reliant on proper care, a nutritious diet, and a suitable living environment.


Caring for a Platinum Arowana requires significant attention due to their size and unique needs. A spacious tank, ideally over 180 gallons, is a necessity to accommodate their active nature. Additionally, these fish are known to jump, so a secure top on the aquarium is essential for their safety.

A carnivorous species, Platinum Arowanas require a protein-rich diet including shrimp, crickets, and small fish. Water conditions should mirror their natural habitat, with temperatures between 75-86°F (24-30°C), pH levels of 6.0-7.0, and consistent filtration for clean water.

While robust, these fish can fall prey to diseases such as fin rot or ich, demanding regular monitoring. Moreover, due to their endangered status, owning a Platinum Arowana necessitates adherence to international and local regulations.

Tank Size For Platinum Arowana

Given the considerable size of a fully grown Platinum Arowana, their tank requirements are also substantial. A mature Platinum Arowana can reach up to 35 inches (90 cm) in length, and as such, it needs plenty of room to swim and turn around comfortably.

A general rule of thumb for Arowana tank sizes is that the tank length should be at least twice as long as the fish’s full adult length. Therefore, for a Platinum Arowana, the tank should ideally be at least 70 inches (178 cm) long.

In terms of volume, considering both the fish’s size and its active nature, a tank of 180 gallons (681 liters) or more is usually recommended. However, larger is always better for these majestic creatures to thrive.

Also, bear in mind that Platinum Arowanas are known jumpers, especially when startled. So, a secure lid or cover is an essential part of the aquarium setup to prevent them from leaping out.

Water Parameters

Maintaining the proper water parameters in a Platinum Arowana’s tank is vital for their health and well-being. Here are the key parameters to keep in mind:

  • Temperature: The water temperature should be kept between 75-86°F (24-30°C). This tropical fish needs warm water to thrive.
  • pH Level: The pH level should ideally be kept between 6.0 and 7.0, replicating the slightly acidic conditions of their natural freshwater habitat.
  • Hardness: Water hardness should be maintained at a level of 5-20 dH, similar to conditions in their native Southeast Asian waters.
  • Ammonia, Nitrite, and Nitrate: Levels of these chemicals should be as low as possible, ideally zero for ammonia and nitrite. Nitrate should be kept below 20 ppm.
  • Water Changes: Regular water changes, typically around 25% per week, are recommended to keep the water clean and maintain these parameters.
  • Filtration: A strong and efficient filtration system is necessary to ensure optimal water quality, removing waste products and preventing the buildup of harmful chemicals.

Always use a good quality water test kit regularly to monitor these parameters. Any sudden or drastic changes in these parameters could stress the fish and lead to health issues.

Things To Put In Their Tank

Setting up a Platinum Arowana tank involves not only the correct water parameters but also the appropriate decorations and items that cater to the Arowana’s natural behaviors and provide a safe and comfortable environment. Here’s what you should consider:

  • Plants: Using live or artificial plants can help replicate a natural environment. However, make sure they don’t take up too much swimming space. Arowanas prefer open spaces.
  • Driftwood and Rocks: A few pieces of driftwood or rocks can create hiding spots and add to the tank’s aesthetics. They should be securely placed so they won’t shift or fall, potentially injuring the fish.
  • Substrate: A fine substrate like sand can be used. However, a bare bottom is also a common choice for easier maintenance, given the large bio-load of this fish.
  • Lighting: Moderate lighting is recommended. Bright lights can cause stress, but too little light won’t show off the Arowana’s stunning colors.
  • Tank Cover: This is a must-have as Arowanas are known jumpers. The cover should be sturdy and secure to prevent the fish from jumping out.
  • Filtration System: A powerful filtration system is necessary to maintain high water quality. It should be efficient in mechanical, chemical, and biological filtration.
  • Heater: To maintain the optimal temperature, a reliable and adjustable heater is needed. Always use a heater guard to prevent the fish from burning itself.

Remember, the Platinum Arowana needs ample open space for swimming. Overcrowding the tank with too many decorations can lead to stress and potential injury.



Platinum Arowanas, like all fish species, are prone to several health issues. Parasitic infections such as Ich or white spot disease are common, presenting as tiny white specks scattered across the fish’s body and fins. Another similar affliction is Velvet disease, characterized by a fine, gold or rust-coloured dusting on the fish.

Bacterial infections also pose a risk. Fin rot is one such ailment, causing the fish’s fin edges to look ragged, often with discolouration. Dropsy, another bacterial condition, results in bloating and a pinecone-like appearance due to protruding scales.

Physical injuries, particularly from jumping, are not uncommon for this species, emphasizing the need for a secure tank lid. Eye issues, like clouding or popping, may also occur.

Regular monitoring for these diseases and maintaining optimal tank conditions is vital. If your Arowana becomes ill, consult with a fish health professional promptly to determine the best treatment.

Platimum Arowana Diet

Platinum Arowanas are carnivorous fish with a preference for high-protein foods. Their natural diet consists of insects, smaller fish, and occasionally crustaceans and amphibians. This feeding habit should be reflected in their diet when kept in captivity.

A variety of live or frozen foods such as shrimp, crickets, mealworms, and small fish like goldfish or guppies can be included in their diet. Specially formulated Arowana pellets, fortified with essential vitamins and minerals, are also a beneficial addition to their feeding regimen.

A key thing to remember is that Arowanas are surface feeders, meaning they’re accustomed to consuming food floating on the water’s surface. Thus, quickly sinking food items may be less suitable. Offering a diverse diet helps ensure their nutritional needs are met and maintains their interest in feeding.

While these fish have hearty appetites, overfeeding should be avoided to prevent health issues and water pollution. Generally, feeding them once or twice a day, with the quantity they can consume in 15-20 minutes, is advised.

Platinum Arowana Behavior & Temperament

Renowned for their majestic presence, Platinum Arowanas are active, robust swimmers that exhibit a keen curiosity about their environment. Predominantly surface dwellers, they spend much of their time in the upper layers of the tank.

These fish are semi-aggressive, displaying territorial tendencies particularly towards other large fish or fellow Arowanas. This behavior can be mitigated to an extent with a spacious tank setup and careful selection of tank mates, to minimize stress and aggression.

Intriguingly, Platinum Arowanas are proficient jumpers, a skill used in the wild for catching prey. In a home aquarium, this trait underscores the need for a sturdy tank lid to prevent injuries or escapes. During feeding, they exhibit hunting behaviors, using their barbels to detect surface movements before swiftly capturing their prey.

Tank Mates

Selecting tank mates for a Platinum Arowana requires deliberation due to the Arowana’s semi-aggressive temperament, considerable size, and specific needs. These carnivorous fish will consume smaller companions, necessitating tank mates of similar size.

Potential tank mates can include larger catfish species, such as the Plecostomus or Asian Bumblebee Catfish. Both provide the advantage of occupying lower tank levels, mitigating territorial disputes with surface-dwelling Arowanas. Certain varieties of cichlids could also cohabitate well, provided they aren’t overly aggressive.

Remember that Arowanas are accustomed to ample swimming space, a requirement that extends to their tank mates. Therefore, the aquarium should be sufficiently spacious to comfortably accommodate all inhabitants without causing stress or territorial disputes.

Despite these guidelines, each fish exhibits individual behaviors and temperaments. Continuous monitoring post-introduction of new tank mates is crucial. If signs of stress, aggression, or distress are noticeable, separating the fish may be necessary for their well-being.


Breeding Platinum Arowanas in captivity is an extremely challenging task, rarely successful even among expert aquarists. This difficulty stems from the specific environmental conditions these fish require and their unique breeding behaviors. Arowanas are mouthbrooders in the wild, with the male carrying the eggs and fry in his mouth for protection until they’re independent.

To stimulate breeding, a pair of Arowanas need a spacious, serene, and stress-free environment. Water conditions mimicking their natural habitat are crucial, along with ensuring the fish are in optimum health. Despite meeting these requirements, breeding success isn’t guaranteed.

Breeding attempts are typically conducted by large commercial breeding facilities due to the resources involved. Identifying the sex of Arowanas is also quite challenging, complicating pairing for breeding. Given these challenges, breeding Platinum Arowanas isn’t a common endeavor for most aquarists.


In the realm of exotic aquatics, Platinum Arowanas stand tall with their mesmerizing beauty and distinct behavior. While their care may seem daunting, understanding their needs and providing a conducive environment can ensure their well-being.

From their unique dietary needs to potential health issues, careful attention is the backbone of responsible Arowana ownership. With the right approach, these majestic creatures can indeed become the crowning jewel of your aquatic collection.
