Can Cockatoo Dwarf Cichlid live with Electric Blue Crayfish?
High risk due to water mismatch, aggression, or predation.
Why Cockatoo Dwarf Cichlid and Electric Blue Crayfish Don't Make an Easy Pair
The size gap is 3.0" — Cockatoo Dwarf Cichlid (3.0") and Electric Blue Crayfish (6.0"). A fish that fits in another fish's mouth will eventually end up there.

Compatibility Breakdown
Temperament Match: semi-aggressive + aggressive. One aggressive → predation/nipping risk.
⚠️ Size Predation Risk: Cockatoo Dwarf Cichlid (3.0") vs Electric Blue Crayfish (6.0"). A 3.0" 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: 45.0/100 (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 80°F.
- pH: maintain 6.5 – 7.5.
- Hiding spots: essential for Cockatoo Dwarf Cichlid — 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 Cockatoo Dwarf Cichlid 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.
