Reporting about three correlated continuity equations which quantify the flux of quantum information in the phase-space, the non-classicality profile of such an anharmonic system can be consistently obtained in terms of the fluxes of {\\em probability}, {\\em purity} and {\\em von Neumann-like entropy}.
