How Many Spotted Congo Puffers Should You Keep?
Spotted Congo Puffers can often be kept singly, in pairs, or even in groups if provided with sufficient space and structure.

- Heavy planting and visual barriers help reduce aggression
Keeping too many puffers in limited space can lead to:
- Territorial disputes
- Fin-nipping
- Stress and injury
Their behaviour is often less aggressive than many other puffer species.

Individual temperament varies, and some fish may become more aggressive than others.
