Experimental programme of eta decays carried out at WASA detector is presented. Not-so-rare eta decays are well suited as a low energy QCD laboratory. For example decay η→3π is a valuable source of information on light quark masses. In very rare eta decays such as η→e+e- and η→π°e+e- fundamental aspects of the Standard Model can be tested. Production reactions – sources of eta mesons for the decay studies at storage rings such as CELSIUS and COSY are discussed. Prospects of eta decay physics for WASA@COSY are presented.
