Set the heater to about 79°F, in the middle of the range they share (76–82°F).
Use a tank of at least 30 gallons. Check the numbers with the stocking calculator.
Keep Congo tetras in a group of 6 or more. A big group is calmer and more colorful.
Add plenty of plants and cover so every fish can get out of sight.
