  We investigate how the ghost condensate reacts to black holes immersed in it.
A ghost condensate defines a hypersurface-orthogonal congruence of timelike
curves, each of which has the tangent vector u^\mu=-g^{\mu\nu}\partial_\nu\phi.
It is argued that the ghost condensate in this picture approximately
corresponds to a congruence of geodesics. In other words, the ghost condensate
accretes into a black hole just like a pressure-less dust. Correspondingly, if
the energy density of the ghost condensate at large distance is set to an
extremely small value by cosmic expansion then the late-time accretion rate of
the ghost condensate should be negligible. The accretion rate remains very
small even if effects of higher derivative terms are taken into account,
provided that the black hole is sufficiently large. It is also discussed how to
reconcile the black hole accretion with the possibility that the ghost
condensate might behave like dark matter.
