Can Clown Loach live with Gold Barb?
Case-by-case. Watch group sizes, tank size, and feeding zones.
Why Clown Loach and Gold Barb Don't Make an Easy Pair
They can coexist, but you need to manage the setup carefully. The temperature margin is tight — only 2°F of safe overlap, which leaves little room for thermostat drift.

Compatibility Breakdown
Temperament Match: peaceful + peaceful. Both peaceful → minimal conflict.
⚠️ Size Predation Risk: Clown Loach (12.0") vs Gold Barb (3.0"). A 9.0" gap — the larger fish will view the smaller fish as food.
Score: 50.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 75 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 75°F and 77°F.
- pH: maintain 6.0 – 7.5.
- Hiding spots: essential for Clown Loach — 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 Clown Loach 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.
