Can Neon Tetra live with YoYo Loach?
High risk due to water mismatch, aggression, or predation.
Why Neon Tetra and YoYo Loach Don't Make an Easy Pair
The size gap is 3.8" — Neon Tetra (1.2") and YoYo Loach (5.0"). A fish that fits in another fish's mouth will eventually end up there.

Compatibility Breakdown
Temperament Match: peaceful + peaceful. Both peaceful → minimal conflict.
⚠️ Size Predation Risk: Neon Tetra (1.2") vs YoYo Loach (5.0"). A 3.8" gap — the larger fish will view the smaller fish as food.
Score: 40.0/100 (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 75°F and 77°F.
- pH: maintain 6.0 – 7.0.
- Hiding spots: essential for Neon 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 peaceful individual Neon 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.
