Throughout the 1980 and 1990s Szafreneck in Germany consistently entered Dwarf Red SJO into the AKA show every year. These had intense orange coloration from the fin into the body, orange it e and fin and orange pecs. The caudal tips never grew extensions and the fish was noticeably smaller in side, more large-gardneri size than typical SJO.
