Both of these fish have very peaceful personalities, however, bolivian rams are certainly more shy than german blue rams are. You will have to provide your bolivians with plenty of hiding spaces to keep them settled.

German blue rams, however, are much more courageous and will spend most of their time swimming frantically around, dancing around, and providing much entertainment for you and their tank mates.

Bolivian rams tend to swim differently too, adopting an unusual swimming technique of three fin strokes and then a pause, before doing it again and again. German blue rams swim around as most fish do.

Tank Requirements

The main difference between both cichlid species is their tank requirements, hardiness, and adaptability. German blue rams need warm water, and their temperature should be between 78-85°F (25.6 to 29.4℃) in order for them to survive. Additionally, they will need a slow-moving current and subdued lighting, their pH level should be in the 6 to 7.5 range. German rams are certainly more fragile than bolivian rams.
