Tetras are generally small fish, but they still require adequate space to swim and explore. A good rule of thumb is to provide at least 10 gallons of water per 10 tetras. A well-planted aquarium with hiding places is essential for their comfort and security. Driftwood, rocks, and caves can create a natural and stimulating environment.

Water Parameters
Most tetra species prefer soft, slightly acidic water. The ideal pH range is between 6.0 and 7.5. Water temperature should be maintained between 72 and 82 degrees Fahrenheit (22-28 degrees Celsius).

Compatibility
Tetras are generally peaceful fish and can be kept with a variety of other community species. However, it’s important to avoid aggressive or large fish that may pose a threat to them. Research the compatibility of any potential tank mates before introducing them to your tetra tank.
