According to Quantum FFF Theory, only (micro) black holes produce plasma which form elongated tails pushing the BHs away from local massive objects.
However in contrast BHs seem to be also attracted to each other like these two and tend to form Herbig Haro systems with star formation or dwarf formation in between.

Pairing micro Black Holes according to the Quantum FFF Model. below:
Plasma tails propelling former starspots ( globules) in the Helix nebula.
Even proplyds seem to have comparable pushing tails.
