The proper "common" name is blue ram since they are not from Germany, but Venezuela and Colombia. They are called German blue rams because before the Asian countries produced the bulk of fish in the trade they were brought back mainly to Germany and bred for the blue color. Although other countries (the Czechs for instance) claim to have been doing it before the Germans.
Chances are nowadays that if you buy a blue ram from you LFS that it has never been to Germany
