Black Skirt Tetra Temperature: Ideal Water Temp
Ideal: 70-80°F (21-27°C)
The Black Skirt Tetra is a tropical species. Aim for the middle of its range, around 75°F, and keep it steady — sudden swings stress fish more than a stable temperature.
You will need a heater to hold 70°F and up in most rooms — use roughly 3-5 watts per gallon plus a separate thermometer.
