Common Mistakes with False Rummy Nose Tetra

✗

Keeping fewer than 6 together

False Rummy Nose Tetra is a schooling species — they need a group of at least 6 to feel secure. Lone or paired individuals become stressed, hide constantly, and may develop health issues or aggression.

✗

Relying on a heater without a thermometer

False Rummy Nose Tetra 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. False Rummy Nose Tetra requires at least 20 gallons — ideally 30. Cramped tanks lead to stunted growth, aggression, and poor water quality.
