High risk due to water mismatch, aggression, or predation.
Why Coral Beauty Angelfish and Zebra Danio Don't Make an Easy Pair
The size gap is 2.0" — Coral Beauty Angelfish (4.0") and Zebra Danio (2.0"). A fish that fits in another fish's mouth will eventually end up there.

Compatibility Breakdown
Temperament Match: semi-aggressive + peaceful. Semi-aggressive → watch territory and feeding.
⚠️ Size Predation Risk: Coral Beauty Angelfish (4.0") vs Zebra Danio (2.0"). A 2.0" gap — the larger fish will view the smaller fish as food.
Score: 0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 30 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 74°F and 75°F.
- pH: no shared range. One species will be outside its tolerance regardless of what you set.
- Hiding spots: essential for Coral Beauty Angelfish — caves, plants, or driftwood to retreat when feeling stressed.
- Water changes: 25% weekly minimum. Two species mean double the bioload.
