Difference between aggression and playing
Neon tetras are non-aggressive fish species that play with each other by chasing each other around the tank.
However, if you see chasing more than often, it can indicate aggression.

In such a case, we recommend placing your aggressive tetra in a separate tank to ensure the well-being of the other fish in the tank.
Consider providing immediate treatment to the injured fish in the tank, as ignoring such a situation can make them weak and prone to several diseases.
Therefore, always provide good housing conditions to your neon tetras to prevent aggression in your fish and ensure their well-being and a longer lifespan.
Conclusion:
- Neon tetras are non-aggressive fish species that like interacting with the other fish species in the tank. However, your fish can get aggressive if placed in inadequate water conditions and due to the irregular food supply.
- Hiding, chasing, and fin-nipping are signs of aggression in your neon tetras.
- Overcrowded tanks, poor water conditions, and stress are some reasons behind the aggressive behavior of your neon tetras.
- Consider providing good water conditions, ample space in the tank, and a stress-free environment to prevent aggression in your fish.
