Bettas are colorful fish that seem like an ornament in the water. They are one of the most popular freshwater fish in the fishkeeping hobby.

There are always things to consider when arranging the aquarium when the Betta will be the star of the tank—including tank mates. Though some fish keepers create Betta community tanks, it is at times best to keep a betta alone, especially for a beginner, since community Betta tanks require space, many live plants, and a somewhat peaceful species of Betta.

Most Betta fins are gorgeous and delicate. They don’t do well with other hostile species of fish because their large flowing fins may become damaged. It is also common to keep a single Betta in the tank because of their aggressive nature.

Their fighting nature has inspired a bad reputation for their tank requirements. Unfortunately, it is a popular trend to keep Bettas in vases and small bowls. A misconception is that a Betta can remain in the cup purchased from the pet store indefinitely (Please don’t do this, the Betta will die.) In reality, they need an average size tank like most fish. Though a five to ten- gallon tank is preferable, a Betta needs at least two and a half gallons to remain healthy.

Now here’s the thing! The tricky part for a fish enthusiast who is designing a large paradise for their Betta and not arranging a betta community tank is that they are left with a lot of space. A single solitary Betta swimming in a large tank can appear empty. There are quite a few popular species of freshwater fish in the hobby, that can harmoniously coexist with Bettas. Remember to consider the needs of each fish species like tank size, temperature, and diet. Here is a list of the best tank mates to place with your Betta in the aquarium.

Bettas have beautiful flowing fins that could be damaged by aggressive fish. Always choose a tank mate that is not hostile.
