Smallest tank

The two fish side by side

Fish	Adult size	Temperature	Min. tank	Keep	Watch for
Betta (male)	2.5 in	76–82°F	5 gal	Alone or as a pair	long fins
German blue ram	2.5 in	78–85°F	20 gal	Alone or as a pair	peaceful

Set the heater to about 80°F, in the middle of the range they share (78–82°F).
Use a tank of at least 20 gallons, and bigger is calmer. Check the numbers with the stocking calculator.
Have a backup plan. Every betta has its own temper, so keep a spare tank or divider ready in case it attacks.
Add plenty of plants and cover so every fish can get out of sight.
