Tetra Fish Species Selection
Tank Size and Compatibility: When selecting the right Tetra species for your fish tank, make sure that your Tetra fish tank size is compatible with the Tetra Fishes. Some tetras thrive better in larger tanks or have a particular preference when it comes to their tank mate choices, whereas others are more adaptable and work well within a community setting.
Water Parameters: Tetra fish require specific water conditions such as temperature, pH level, and water hardness.

Behavior and Activity Level: Each Tetra has unique tendencies when it comes down to behavior patterns and activity levels.
