Common Mistakes with Clown Loach

✗

Keeping fewer than 5 together

Clown Loach is a schooling species — they need a group of at least 5 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

Clown Loach needs 77–86°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 75 gallons

Many beginners underestimate tank size needs. Clown Loach requires at least 75 gallons — ideally 125. Cramped tanks lead to stunted growth, aggression, and poor water quality.
