Common Mistakes with Flavescent Peacock

✗

Relying on a heater without a thermometer

Flavescent Peacock needs 75–82°F. Heaters malfunction or drift over time — always use a separate thermometer to verify. Temperature swings of even 3–4°F can trigger stress and disease, particularly ich.

✗

Putting them in a tank under 20 gallons

Many beginners underestimate tank size needs. Flavescent Peacock requires at least 20 gallons — ideally 30. Cramped tanks lead to stunted growth, aggression, and poor water quality.

✗

Housing with peaceful nano fish

Flavescent Peacock is semi-aggressive and territorial — small, peaceful species like neon tetras, endlers, or celestial pearl danios will be stressed, bullied, or eaten. Choose tank mates that can hold their own.
