Among Metynnis, they mostly all get along and become groups. However, depending of ratio of males/females in a particular group, the 5-6 fish can be very peaceful and harmonious, but also very rambunctious; regardless of species. Easiest is when more females in the group. In addition, too small a tank is usually the limiting factor. What size is your tank?
Footprint is most important - No less than 4 feet tank, better 6 or more.

This is a group of eight adult Metynnis, 3 species:
2 male, 1 female M. maculatus
2 male, 2 female M. lippincotianus
1 male, M. altidorsalis
