Can Black Skirt Tetra live with Tiger Barb?
These two species are usually compatible in community tanks.
Why Black Skirt Tetra and Tiger Barb Work
These two species overlap in both temperature (74–79°F overlap) and pH (6.0-7.0 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 + semi-aggressive) is low-conflict. In a 20+ gallon tank with adequate hiding spots, these two can coexist with minimal problems.

Compatibility Breakdown
Temperament Match: semi-aggressive + semi-aggressive. Semi-aggressive → watch territory and feeding.
Score: 80.0/100 (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 74°F and 79°F.
- pH: maintain 6.0 – 7.0.
- Hiding spots: essential for Black Skirt Tetra — 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 Black Skirt Tetra 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.
