Angelfish Temperature: Ideal Water Temp
Ideal: 76-84°F (24-29°C)
The Angelfish is a tropical species. Aim for the middle of its range, around 80°F, and keep it steady — sudden swings stress fish more than a stable temperature.
You will need a heater to hold 76°F and up in most rooms — use roughly 3-5 watts per gallon plus a separate thermometer.
