Can Dwarf Gourami live with German Blue Ram?
These two species are usually compatible in community tanks.
Why Dwarf Gourami and German Blue Ram Work
These two species overlap in both temperature (78–82°F overlap) and pH (6.5-7.0 overlap range). Their temperature tolerances are close enough, and neither fish pushes the pH so far outside the other's comfort zone that it creates chronic stress. The temperament match (peaceful + peaceful) is low-conflict. In a 20+ gallon tank with adequate hiding spots, these two can coexist with minimal problems.

Compatibility Breakdown
Temperament Match: peaceful + peaceful. Both peaceful → minimal conflict.
Score: 80.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 20 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 78°F and 82°F.
- pH: maintain 6.5 – 7.0.
- 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.
