Migos Massive Brawl With Fans During Nashville Show

"Versace" rappers Migos got into an all-out battle royale at one of their shows ... where all 3 members of the group ended up going loco on their fans.
The melee started Sunday night at LimeLight nightclub in Nashville -- when according to sources ... one member of the group had a gold chain snatched from his neck while on stage, and immediately went after it in the crowd.
It's pretty wild fight video -- bodies pile up on the floor as the whole thing plays out.

Police were called, but LimeLight security was eventually able to contain things and no arrests were made.
