In the world of Aquarium keeping, enthusiasts often wonder if it is possible to mix different species of fish together. One popular question that arises is whether it is feasible to keep sharks and arowanas in the same aquarium. In this comprehensive guide, we will delve into the Compatibility, care requirements, and potential challenges of mixing these two fascinating aquatic creatures. Accompanied by a collection of high-quality images, this article aims to provide a detailed insight into the topic.


Sharks and arowanas belong to different families and have distinct characteristics, making their compatibility in the same aquarium a subject of concern. Sharks are known for their aggressive behavior, territorial nature, and predatory instincts. On the other hand, arowanas are known for their territorial behavior.and their ability to grow to a considerable size. Due to these attributes, it is generally not recommended to mix sharks and arowanas in the same tank.

tank size and Setup:

Both sharks and arowanas require large aquariums to accommodate their size and swimming needs. Sharks, depending on the species, can grow significantly larger than arowanas. Therefore, a tank size of at least 200 gallons (757 liters) is recommended for sharks, while arowanas require a tank size of around 100 gallons (378 liters) for smaller species and even larger tanks for larger species. The tank should be equipped with appropriate filtration systems to maintain water quality, as both species produce a significant amount of waste.

Water Parameters:

Maintaining suitable water parameters is crucial for the well-being of both sharks and arowanas. Sharks prefer a slightly alkaline pH ranging from 7.5 to 8.4 and a temperature between 72°F to 82°F (22°C to 28°C). Arowanas, on the other hand, thrive in slightly acidic to neutral pH levels between 6.5 to 7.5 and a temperature range of 75°F to 82°F (24°C to 28°C). It is important to ensure that the water parameters are within the acceptable range for both species to minimize stress and potential health issues.


Sharks are carnivorous predators and require a diet consisting of meaty foods such as fish, shrimp, and squid. Arowanas are also carnivorous and primarily Feed on small fish, insects, and crustaceans. While their dietary requirements.may overlap to some extent, it is crucial to consider the size difference between the two species. Sharks may view arowanas as potential prey, leading to aggression and potential harm to the arowanas. Therefore, it is advisable to provide separate feeding areas or individualize their feeding schedules to prevent any conflicts.

Behavior and Aggression:

As mentioned earlier, both sharks and arowanas can display territorial behavior, which can lead to aggression when housed together. Sharks are known to be aggressive towards other fish, especially those of similar size or smaller. Arowanas, although generally peaceful, can become territorial and aggressive towards tank mates, particularly when they feel threatened or their space is invaded. Mixing these two species may result in constant stress, aggression, and potential injuries to either or both fish.

Challenges and Considerations:

Mixing sharks and arowanas in the same aquarium poses several challenges and considerations. The vast difference in size, territorial behavior, and potential aggression can lead to an unhealthy and hostile environment for both species. Furthermore, the cost of maintaining a large enough tank with suitable filtration systems and providing appropriate diets for both sharks and arowanas can be financially burdensome.


In conclusion, while it may be possible to mix sharks and arowanas in the same aquarium under specific circumstances, it is generally not recommended due to the significant differences in their care requirements, behavior, and potential aggression. It is crucial to prioritize the well-being and safety of the fish when considering tank mates. Therefore, it is advisable to provide suitable tank setups and companions that are compatible with each species' specific needs.
