Can Clown Loach live with Platy?
High risk due to water mismatch, aggression, or predation.
Why Clown Loach and Platy Don't Make an Easy Pair
The size gap is 9.5" — Clown Loach (12.0") and Platy (2.5"). 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: Clown Loach (12.0") vs Platy (2.5"). A 9.5" gap — the larger fish will view the smaller fish as food.
Score: 30.0/100 (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 7.0 – 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.
