We demonstrate that the anisotropic stress-energy supporting the Kiselevblack hole can be mimicked by being split into a perfect fluid component pluseither an electromagnetic component or a scalar field component, therebyquantifying the precise extent to which the Kiselev black hole fails torepresent a perfect fluid spacetime. The perfect fluid component carries eitheran electric or a scalar charge, which then generates anisotropicelectromagnetic or scalar fields. This in turn generates anisotropiccontributions to the stress-energy. These in turn induce forces which partially(in addition to the fluid pressure gradient) support the matter content againstgravity. This decomposition is carried out both for the original 1-componentKiselev black hole and for the generalized N-component Kiselev black holes. Wealso comment on the presence of energy condition violations (specifically forthe null energy condition --- NEC) for certain sub-classes of Kiselev blackholes.
