Choosing The Right Puffer Species
Puffers are unique fish with special care needs. Choosing the right species helps keep them healthy.
Different puffers live in freshwater or brackish water. Their size and behavior also vary a lot.
Freshwater Vs. Brackish Puffers
Freshwater puffers live in rivers and lakes. Brackish puffers need water that is partly salty. This affects tank setup and care.
- Freshwater puffers are easier to care for in home tanks.
- Brackish puffers need salt added to their water.
- Some species can live in both, but check carefully.
- Water quality is very important for both types.
Size And Behavior Considerations
| Species | Average Size | Temperament |
| Green Spotted Puffer | 6 inches | Active and aggressive |
| Figure Eight Puffer | 4 inches | Shy but territorial |
| Amazon Puffer | 7 inches | Calm and slow |
| Figure Eight Puffer | 4 inches | Shy but territorial |
Large puffers need bigger tanks. Some puffers are aggressive and may attack others.
Compatibility With Other Fish
Puffers often do not get along with other fish. They can be territorial and bite fins.
Tips for keeping puffers with other fish:
- Choose fast or armored fish species
- Avoid slow or long-finned fish
