Can Dwarf Pufferfish live with Zebra Danio?
High risk due to water mismatch, aggression, or predation.
Why Dwarf Pufferfish and Zebra Danio Don't Make an Easy Pair
There is no temperature overlap — Dwarf Pufferfish needs 75-82°F while Zebra Danio needs 64-75°F. One of them will be outside its safe range constantly, which leads to chronic stress and disease.

Compatibility Breakdown
Temperament Match: semi-aggressive + peaceful. Semi-aggressive → watch territory and feeding.
Score: 30.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 10 gallons — sized for the larger fish in the pair.
- Temperature: no safe overlap range exists. A heater is not enough to fix this pairing.
- pH: maintain 7.0 – 7.5.
- 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.
