Can Cherry Shrimp live with German Blue Ram?
High risk due to water mismatch, aggression, or predation.
Why Cherry Shrimp and German Blue Ram Don't Make an Easy Pair
There is no temperature overlap — Cherry Shrimp needs 64-76°F while German Blue Ram needs 78-86°F. One of them will be outside its safe range constantly, which leads to chronic stress and disease.

Score: 40.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 20 gallons — sized for the larger fish in the pair.
- Temperature: no safe overlap range exists. A heater is not enough to fix this pairing.
- pH: maintain 6.5 – 7.0.
- 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.
