Can Mystery Snail live with Zebra Danio?
These two species are usually compatible in community tanks.
Why Mystery Snail and Zebra Danio Work
These two species overlap in both temperature (68–75°F overlap) and pH (7.0-7.5 overlap range). Their temperature tolerances are close enough, and neither fish pushes the pH so far outside the other's comfort zone that it creates chronic stress. The temperament match (peaceful + peaceful) is low-conflict. In a 10+ gallon tank with adequate hiding spots, these two can coexist with minimal problems.

Compatibility Breakdown
Temperament Match: peaceful + peaceful. Both peaceful → minimal conflict.
Score: 110.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 10 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 68°F and 75°F.
- pH: maintain 7.0 – 7.5.
- Hiding spots: essential for Mystery Snail — 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 Mystery Snail 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.
