The anisotropic flow of identified particles is an important observable to test the collective behavior of the matter created in heavy-ion collisions. We report on the first measurements of elliptic and triangular flow for charged pions, kaons and protons in lead-lead collisions at 2.76 TeV per nucleon pair center of mass energy, measured with the ALICE detector at the LHC. We will make a detailed comparison of the observed mass splitting of v_{2} at LHC energies to RHIC measurements at lower energies. For identified particles with intermediate transverse momenta we test the quark coalescence picture with v_{2} and v_{3} scaled by the number of constituent quarks vs scaled p_{t} and scaled m_{t}.
