Pictus Catfish Temperature: Ideal Water Temp
Ideal: 75-81°F (24-27°C)
The Pictus Catfish is a tropical species. Aim for the middle of its range, around 78°F, and keep it steady — sudden swings stress fish more than a stable temperature.
You will need a heater to hold 75°F and up in most rooms — use roughly 3-5 watts per gallon plus a separate thermometer.
