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

Compatibility Breakdown
Temperament Match: semi-aggressive + peaceful. Semi-aggressive → watch territory and feeding.
⚠️ Size Predation Risk: Electric Blue Acara (6.0") vs Weather Loach (10.0"). A 4.0" gap — the larger fish will view the smaller fish as food.
⚠️ Diet Conflict: A carnivore sharing water with a fish small enough to fit in its mouth is a waiting game. Feed generously, but the risk is structural — not something you can manage meal by meal.
Score: 60.0/100 (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 72°F and 77°F.
- pH: maintain 6.5 – 7.5.
- Hiding spots: essential for Electric Blue Acara — 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 Electric Blue Acara 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.
