Can Dwarf Gourami live with Firemouth Cichlid?
Case-by-case. Watch group sizes, tank size, and feeding zones.
Why Dwarf Gourami and Firemouth Cichlid Don't Make an Easy Pair
They can coexist, but you need to manage the setup carefully. The temperament combination (peaceful+semi-aggressive) can work, but you will need to watch them at feeding time for the first week.

Compatibility Breakdown
Temperament Match: peaceful + semi-aggressive. Semi-aggressive → watch territory and feeding.
⚠️ Size Predation Risk: Dwarf Gourami (3.5") vs Firemouth Cichlid (6.0"). A 2.5" gap — the larger fish will view the smaller fish as food.
Score: 60.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 30 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 77°F and 82°F.
- 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.
