Common Mistakes with Striped Raphael Catfish
Relying on a heater without a thermometer
Striped Raphael Catfish 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 40 gallons
Many beginners underestimate tank size needs. Striped Raphael Catfish requires at least 40 gallons — ideally 60. 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 Striped Raphael Catfish for 2–4 weeks in a separate tank before adding to your main aquarium.
