Common Mistakes with Starlight Bristlenose

✗

Relying on a heater without a thermometer

Starlight Bristlenose 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. Starlight Bristlenose requires at least 20 gallons — ideally 30. 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 Starlight Bristlenose for 2–4 weeks in a separate tank before adding to your main aquarium.
