How many German blue rams should be kept together?

At least two German blue rams should be kept together in a tank. German blue rams are at their best when living with their mates, so try to keep both males and females.

German blue rams are monogamous and mate for life. Buying German blue ram pairs while they’re still young is recommended. That way, they can bond together before reaching sexual maturity.

Also, keep in mind that German blue rams require plenty of space, despite their small size. A single German blue ram needs at least 10 gallons of space. You’ll need a 20-gallon tank or bigger to keep a pair of German blue rams.
