Case-by-case. Watch group sizes, tank size, and feeding zones.
Why Cherry Shrimp and Rummy-Nose Tetra Don't Make an Easy Pair
They can coexist, but you need to manage the setup carefully. The temperature margin is tight — only 1°F of safe overlap, which leaves little room for thermostat drift.

Score: 50.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 20 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 75°F and 76°F.
- 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.
