Can Coral Beauty Angelfish live with Goldfish?
High risk due to water mismatch, aggression, or predation.
Why Coral Beauty Angelfish and Goldfish Don't Make an Easy Pair
There is no temperature overlap — Coral Beauty Angelfish needs 74-82°F while Goldfish needs 62-74°F. One of them will be outside its safe range constantly, which leads to chronic stress and disease. The size gap is 6.0" — Coral Beauty Angelfish (4.0") and Goldfish (10.0"). 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 Goldfish (10.0"). A 6.0" gap — the larger fish will view the smaller fish as food.
Score: -10/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 30 gallons — sized for the larger fish in the pair.
- Temperature: no safe overlap range exists. A heater is not enough to fix this pairing.
- 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.

Accuracy note: This tool uses expert rules + FishBase.org data. Individual fish behavior varies — a semi-aggressive individual Coral Beauty Angelfish 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.
