What are the best tank mates for Anabas to reduce aggression?

Are you struggling to find the perfect tank mates for your Anabas fish? Maintaining a harmonious aquarium environment can be challenging, especially when dealing with the natural aggressive tendencies of Anabas. However, with the right mix of tank mates, you can reduce aggression and create a peaceful cohabitation. Some of the best tank mates for Anabas include peaceful species such as gouramis, barbs, danios, and loaches. These fish are not only compatible with Anabas but can also help reduce its aggressive behavior. It is important to carefully consider the temperament and size of potential tank mates to ensure a successful and harmonious aquarium community.

Criteria for Selecting Compatible Tank Mates

When selecting tank mates for your Anabas, it’s important to consider a few key criteria to ensure compatibility and reduce aggression. By choosing the right companions for your Anabas, you can create a harmonious and thriving aquatic environment.

Tank Size Requirements

One of the most important factors to consider when choosing tank mates for your Anabas is the size of your aquarium. Anabas are territorial and can become aggressive if they feel cramped in a small space. You should aim for a tank size of at least 30 gallons for a single Anabas, with additional gallons per fish if you plan to add more individuals. A larger tank will provide enough space for each fish to establish their territory and reduce the likelihood of aggressive behavior.

Complementary Temperaments and Behaviors

When introducing tank mates to your Anabas, it’s crucial to consider their temperaments and behaviors. Look for species that are peaceful and non-aggressive, as they are less likely to provoke your Anabas. Additionally, consider the swimming level and habits of the potential tank mates. Choosing species that inhabit different areas of the tank, such as bottom-dwellers or mid-water swimmers, can help reduce competition for space and resources.

Recommended Tank Mates for Anabas

Some fish are more suitable tank mates for Anabas, as they are less likely to provoke aggression or territorial behavior. When selecting tank mates for your Anabas, it’s crucial to consider the compatibility of the other fish species with the Anabas’ aggressive tendencies. Here are some recommended tank mates that can help reduce aggression in Anabas.

Peaceful Fish Species

If you want to minimize the potential for conflict in your aquarium, consider adding peaceful fish species as tank mates for your Anabas. Peaceful fish, such as guppies, mollies, platies, and tetras, are less likely to incite aggression in Anabas. These species are known for their calm and non-threatening behavior, making them ideal companions for your Anabas. Additionally, their vibrant colors and active swimming patterns can enhance the overall aesthetic appeal of your aquarium, creating a harmonious and visually appealing aquatic environment.

Bottom Dwellers and Algae Eaters

When choosing tank mates for your Anabas, you may want to consider adding bottom dwellers and algae eaters to your aquarium. Species such as Corydoras catfish, Bristlenose plecos, and Siamese algae eaters can help maintain a clean and healthy environment by consuming leftover food, detritus, and algae. Their presence can also help to create a balanced ecosystem within your aquarium, reducing the likelihood of territorial disputes or aggressive behavior from your Anabas. However, it’s essential to provide ample hiding places and territories for these bottom-dwelling species to avoid potential conflicts with your Anabas.

Factors to Consider When Introducing New Tank Mates

Despite the peaceful nature of Anabas, introducing new tank mates can still be a delicate process. There are several factors to consider before adding any new fish to the tank to reduce the risk of aggression and ensure the well-being of the Anabas and its tank mates. Here are the key points to keep in mind:

  • Size and Temperament: Ensure that the new tank mates are of a similar size and temperament to the Anabas to minimize any potential conflicts.
  • Adequate Space: Provide enough hiding spaces and territories within the tank to reduce aggressive behaviors and give the fish a sense of security.
  • Species Compatibility: Research the compatibility of the species and their specific requirements to create a harmonious tank environment.
  • Observation: Keep a close eye on the interactions between the Anabas and the new tank mates to identify any signs of aggression or stress.

Though introducing new tank mates can be challenging, taking these factors into account will greatly increase the chances of successful cohabitation.

Acclimation and Quarantine Processes

When introducing new tank mates to your Anabas, it is crucial to implement acclimation and quarantine processes to minimize stress and the risk of introducing diseases to your existing fish. Acclimating the new fish to the tank water and ensuring they are healthy through quarantine will help create a safe environment for all your aquatic pets.

Monitoring Interactions and Establishing Hierarchies

After introducing new tank mates to your Anabas, it is important to closely monitor their interactions to observe any signs of aggression or territorial behavior. It is natural for fish to establish hierarchies, but if aggressive behavior becomes frequent or intense, intervention may be necessary to ensure the well-being of all the fish in the tank.

Creating a Harmonious Aquatic Environment

Now that you’ve decided to keep Anabas in your aquarium, it’s important to create a harmonious aquatic environment that will help reduce aggression among tank mates. By taking the right steps, you can ensure that your Anabas and its tank mates coexist peacefully, creating a thriving ecosystem within your aquarium.

Habitat Enrichment and Hiding Spots

To reduce aggression among tank mates, it’s crucial to provide hiding spots and habitat enrichment within your aquarium. You can achieve this by adding live or artificial plants, rocks, and driftwood. Creating hiding spots allows Anabas and other fish to have their own territories within the tank, minimizing potential conflicts. Additionally, consider adding caves or other structures that provide secluded areas for fish to retreat to when they feel threatened. This will give your Anabas and its tank mates a sense of security and help reduce aggression in the long run.

Maintaining Water Quality and Diet

Maintaining optimal water quality is essential for minimizing stress and aggression among tank mates. Ensure that you regularly monitor and maintain proper pH, ammonia, nitrite, and nitrate levels in the aquarium. In addition to maintaining water quality, it’s important to provide a balanced diet for your Anabas and its tank mates. A well-fed fish is less likely to exhibit aggressive behavior. Offer a variety of foods, including high-quality pellets, live or frozen foods, and fresh vegetables, to ensure that all fish in the tank are well-nourished and content.


Summing up, when it comes to choosing tank mates for Anabas to reduce aggression, you should consider peaceful and non-aggressive fish that inhabit different areas of the tank. This will help reduce competition for space and resources, ultimately lowering the likelihood of aggression. Additionally, choosing fish with similar water parameter requirements and avoiding species that are known to provoke or intimidate Anabas will also contribute to a harmonious tank environment. By carefully selecting the right tank mates, you can create a peaceful and thriving community aquarium for your Anabas.


Q: What are the best tank mates for Anabas to reduce aggression?

A: Anabas, also known as the climbing perch, can be aggressive towards other fish, so the best tank mates are typically peaceful, non-aggressive species. Some suitable tank mates for Anabas include gouramis, mollies, swordtails, and certain types of catfish. It’s important to provide enough space and hiding spots in the tank to minimize potential conflicts.
