In an expanding plasma, non-zero shear viscosity implies an anisotropic momentum distribution of particles in a fluid cell. This leads to anisotropic screening of static electric fields. I present a simple model for the static potential between infinitely heavy fundamental charges which includes the Coulomb as well as the string force and is easily extended to anisotropic plasmas. Finally, I show the binding energies of 1S/1P charmonium and bottomonium states and the polarization of 1P bb_bar states in the deconfined phase obtained from this potential.
