We show that non-Hermitian and nearest-neighbor-interacting perturbations to the Fritzsch textures of lepton and quark mass matrices can make both of them fit current experimental data very well. In particular, we obtain theta(23) similar or equal to 45 degrees for the atmospheric neutrino mixing angle and predict theta(13) similar or equal to 3 degrees to 6 degrees for the smallest neutrino mixing angle when the perturbations in the lepton sector are at the 20% level. The same level of perturbations is required in the quark sector, where the Jarlskog invariant of CP violation is about 3.7 x 10(-5). In comparison, the strength of leptonic CP violation is possible to reach about 1.5 x 10(-2) in neutrino oscillations. (C) 2011 Elsevier B.V. All rights reserved.
