Proper care of neon tetras requires careful consideration of their environment, water parameters, diet, and social needs to ensure them a healthy and fulfilling life.

An aquarium with a length of 60 cm or more is recommended. The aquarium should be well planted to provide hiding places and protection. The substrate can consist of fine gravel or sand.
- Water quality and parameters: Neon fish prefer soft, slightly acidic water. The pH value should be between 6,0 and 7,5, the water hardness between 2 and 10 dH. Regular water maintenance with a water change of about 20-30% per week is essential to maintain optimal conditions.
- Water temperature: The ideal temperature for tetras is between 22 and 26 degrees Celsius. Water that is too cold or too warm can lead to stress and illness.

- Social behaviour: Due to their swarming behavior, neon tetras should be kept in a sufficiently large group. A small swarm can lead to stress and behavioral problems. They can be socialized well with other peaceful fish species of a similar size, but should be protected from aggressive or larger species.
- Behavior and environment: Neon tetras are most active at dusk and early morning. Provide them with enough hiding spots and plants to make them feel safe. Monitor their behavior regularly for signs of stress, illness, or behavioral changes.
- Water change and care: Regular water changes, removal of excess food and cleaning of the substrate are necessary to keep the water quality optimal.
