Can Dwarf Gourami live with White Cloud Minnow?
High risk due to water mismatch, aggression, or predation.
Why Dwarf Gourami and White Cloud Minnow Don't Make an Easy Pair
There is no temperature overlap — Dwarf Gourami needs 77-82°F while White Cloud Minnow needs 60-75°F. One of them will be outside its safe range constantly, which leads to chronic stress and disease. The size gap is 2.0" — Dwarf Gourami (3.5") and White Cloud Minnow (1.5"). A fish that fits in another fish's mouth will eventually end up there.

Compatibility Breakdown
Temperament Match: peaceful + peaceful. Both peaceful → minimal conflict.
⚠️ Size Predation Risk: Dwarf Gourami (3.5") vs White Cloud Minnow (1.5"). A 2.0" gap — the larger fish will view the smaller fish as food.
Score: 20.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 20 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 6.5 – 7.5.
- Hiding spots: essential for Dwarf Gourami — 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 peaceful individual Dwarf Gourami 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.
