Can Electric Yellow Lab live with Hillstream Loach?
High risk due to water mismatch, aggression, or predation.
Why Electric Yellow Lab and Hillstream Loach Don't Make an Easy Pair
There is no temperature overlap — Electric Yellow Lab needs 75-82°F while Hillstream Loach needs 64-75°F. One of them will be outside its safe range constantly, which leads to chronic stress and disease.

Water Parameter Overlap
| Parameter | Electric Yellow Lab | Hillstream Loach | Overlap |
|---|---|---|---|
| Temperature | 75-82°F | 64-75°F | No overlap ✗ |
| pH | 7.8-8.6 | 6.5-7.5 | No overlap ✗ |
Compatibility Breakdown
Temperament Match: semi-aggressive + peaceful. Semi-aggressive → watch territory and feeding.
Score: 20/100 (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 Electric Yellow Lab — caves, plants, or driftwood to retreat when feeling stressed.
- Water changes: 25% weekly minimum. Two species mean double the bioload.

⚠️ Common Reasons This Pairing Fails in Practice
- Zero temperature overlap: No heater setting can satisfy both species. One will be chronically stressed, leading to disease susceptibility.
- Overcrowding: Even compatible species fail in tanks that are too small. Double the species means double the bioload — 25% weekly water changes are the minimum.
- Inadequate acclimation: Adding both species on the same day without quarantine is a common mistake. Always drip-acclimate new arrivals and quarantine for 2–4 weeks.
- Mismatched feeding: Electric Yellow Lab is a omnivore while Hillstream Loach is a herbivore. Use targeted feeding zones and sinking vs. floating food to ensure both get proper nutrition.
Tools & Resources
Accuracy note: This tool uses expert rules + FishBase.org data. Individual fish behavior varies — a semi-aggressive individual Electric Yellow Lab 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.
