Can Tetras Live with Bettas in the Aquarium?

Can tetras live with betta fish? Many fishkeepers wonder if it’s possible to keep neon tetras and bettas in the same tank. The answer is complex, as it depends on the specific dynamics of your aquarium.

Bettas, especially males, are known to be territorial. In a small tank like a 5 or even 10-gallon tank, it may be challenging to house tetras and bettas together without issues.

Can Neon Tetras Eat Betta Food

Tetras could nip the betta fins, causing stress and harm. However, in a larger tank, such as a 20 gallon or more, with plenty of hiding spots and live plants, it may be possible to keep these fish species together. It is essential to monitor their behavior and make adjustments if needed.

Additionally, it’s crucial to meet the specific needs of each type of fish. Tetras must be in a schooling fish group, whereas bettas are typically solitary. Tetras also need at least a ten gallon tank to thrive, as they are active swimmers.

Some types of tetras need a tank with a stable cycle and water test for parameters. On the other hand, bettas can survive in smaller tanks but still need enough space to swim freely.

Ultimately, the compatibility of tetras and betta fish as tankmates will depend on your specific setup and the individual temperaments of the fish involved.

If you have a betta fish and want to add some companions to its tank, a few species can coexist peacefully. Choosing tankmates with similar care requirements is essential and will not provoke aggression in your betta.

Here are three species of fish that can happily live alongside tanks with a betta fish:

Corydoras Catfish

  • Corydoras catfish are peaceful bottom feeders native to small streams and rivers in South America.
  • They are scavengers and will help to clean up any leftover food that settles at the bottom of the tank.
  • Corydoras catfish are schooling fish, so keeping them in groups of 5 or more is best.
  • Minimum tank size: 10 gallons per 6 Corydoras catfish

Harlequin Rasboras

  • Harlequin Rasboras are small, peaceful fish that are native to Southeast Asia.
  • They are very colorful and come in various colors, including red, orange, purple, and blue.
  • Harlequin Rasboras are schooling fish, so keeping them in groups of 6 or more is best.
  • Minimum tank size: 10 gallons per 6 harlequin Rasboras

Amano Shrimp

  • Amano shrimp are peaceful shrimp that are native to Japan.
  • They are excellent algae eaters and will help to keep your tank clean.
  • Amano shrimp are not schooling fish, but keeping them in groups of 5 or more is best.
  • Minimum tank size: 10 gallons per 5 Amano shrimp

Important things to consider before housing any fish with your betta fish:

  • Temperament: It is essential to choose peaceful tank mates that are unlikely to harass your betta.
  • Water parameters: Make sure that the water parameters for your betta are compatible with the water parameters for the fish you want to house with it.
