A fluid by definition will not have a bulk modulus since it will deform instantanuously and irreviersibly when exposed to a shear. It will however, have a viscosity which determines how much it will deform when exposed to a shear. If it is viscoelastic it will have both a storage (elastic) and loss (viscous) modulus. --- "Nathan L.
