Common Mistakes with Pearl Gourami

✗

Relying on a heater without a thermometer

Pearl Gourami needs 77–82°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 30 gallons

Many beginners underestimate tank size needs. Pearl Gourami requires at least 30 gallons — ideally 40. Cramped tanks lead to stunted growth, aggression, and poor water quality.

✗

Skipping the quarantine period

Even healthy-looking fish can carry parasites or disease. Quarantine new Pearl Gourami for 2–4 weeks in a separate tank before adding to your main aquarium.
