Can Dwarf Pufferfish live with Neon Tetra?
High risk due to water mismatch, aggression, or predation.
Why Dwarf Pufferfish and Neon Tetra Don't Make an Easy Pair
The temperament mismatch (semi-aggressive + peaceful) makes this a high-risk pairing. Injuries, stress, and hiding behavior are likely.

Water Parameter Overlap
| Parameter | Dwarf Pufferfish | Neon Tetra | Overlap |

Compatibility Breakdown
Temperament Match: semi-aggressive + peaceful. Semi-aggressive → watch territory and feeding.
Score: 40/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 10 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 75°F and 77°F.
- pH: no shared range. One species will be outside its tolerance regardless of what you set.
- Hiding spots: essential for Dwarf Pufferfish — caves, plants, or driftwood to retreat when feeling stressed.
- Water changes: 25% weekly minimum. Two species mean double the bioload.

Accuracy note: This tool uses expert rules + FishBase.org data. Individual fish behavior varies — a semi-aggressive individual Dwarf Pufferfish may act differently from its species average. Always observe, quarantine new arrivals for 2-4 weeks, and avoid overcrowding. If a pairing says CAUTION, start with a smaller group and a lid.
