Can Cherry Shrimp live with Flowerhorn?
High risk due to water mismatch, aggression, or predation.
Why Cherry Shrimp and Flowerhorn Don't Make an Easy Pair
There is no temperature overlap — Cherry Shrimp needs 64-76°F while Flowerhorn needs 78-86°F. One of them will be outside its safe range constantly, which leads to chronic stress and disease. The size gap is 10.8" — Cherry Shrimp (1.2") and Flowerhorn (12.0"). A fish that fits in another fish's mouth will eventually end up there.

Compatibility Breakdown
Temperament Match: peaceful + aggressive. One aggressive → predation/nipping risk.
⚠️ Size Predation Risk: Cherry Shrimp (1.2") vs Flowerhorn (12.0"). A 10.8" gap — the larger fish will view the smaller fish as food.
⚠️ Diet Conflict: A carnivore sharing water with a fish small enough to fit in its mouth is a waiting game. Feed generously, but the risk is structural — not something you can manage meal by meal.
Score: 5.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 75 gallons — sized for the larger fish in the pair.
- Temperature: no safe overlap range exists. A heater is not enough to fix this pairing.
- pH: maintain 6.5 – 7.5.
- Hiding spots: essential for Cherry Shrimp — 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 Cherry Shrimp 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.
