Common Mistakes with Apistogramma Agassizii

✗

Relying on a heater without a thermometer

Apistogramma Agassizii needs 72–82°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. Apistogramma Agassizii requires at least 20 gallons — ideally 30. Cramped tanks lead to stunted growth, aggression, and poor water quality.

✗

Housing with peaceful nano fish
