Can Bala Shark live with Neon Tetra?
Case-by-case. Watch group sizes, tank size, and feeding zones.
Why Bala Shark and Neon Tetra Don't Make an Easy Pair
They can coexist, but you need to manage the setup carefully. The temperament combination (peaceful+peaceful) can work, but you will need to watch them at feeding time for the first week.

Compatibility Breakdown
Temperament Match: peaceful + peaceful. Both peaceful → minimal conflict.
⚠️ Size Predation Risk: Bala Shark (14.0") vs Neon Tetra (1.2"). A 12.8" gap — the larger fish will view the smaller fish as food.
Score: 70.0/100 (GOOD ≥80, CAUTION ≥50, RISKY <50).
🔧 Tank Setup Requirements (for Both)
- Minimum tank: 150 gallons — sized for the larger fish in the pair.
- Temperature: keep it between 72°F and 77°F.
- pH: maintain 6.0 – 7.0.
- Hiding spots: essential for Bala Shark — 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 Bala Shark 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.
