We study hydrodynamic properties of an expanding YM-theory plasma by using AdS/CFT. The expansion we consider is the Bjorken\'s one-dimensional expansion which is relevant to RHIC and LHC physics. The holographic dual of the plasma is believed to be a time-dependent black hole in an asymptotically AdS spacetime, however nobody has been checked the presence of the horizon explicitly so far. We explicitly construct the dual geometry on Eddington-Finkelstein coordinates and show that it has an (time-dependent) apparent horizon. We will also discuss, if possible, that the ``cosmic censorship\'\' may be a criteria for physical dual geometry, and how the transport coefficients of the fluid can be determined by the geometry without based on the linear response theory. We hope this work may shed some light on a way to compute anomalous viscosity of the fluid.
