Can Blood Parrot Cichlid live with Threadfin Butterflyfish?
These two species are usually compatible in community tanks.
Why Blood Parrot Cichlid and Threadfin Butterflyfish Work
These two species overlap in both temperature (76–82°F overlap) and pH (- 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 (semi-aggressive + peaceful) is low-conflict. In a 75+ gallon tank with adequate hiding spots, these two can coexist with minimal problems.

Water Parameter Overlap
| Parameter | Blood Parrot Cichlid | Threadfin Butterflyfish | Overlap |

| pH | 6.5-7.5 | 8.1-8.4 | No overlap ✗ |
Compatibility Breakdown
Temperament Match: semi-aggressive + peaceful. Semi-aggressive → watch territory and feeding.
Score: 80/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 75 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 76°F and 82°F.
- pH: no shared range. One species will be outside its tolerance regardless of what you set.
- Hiding spots: essential for Blood Parrot Cichlid — 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 Blood Parrot Cichlid 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.
