  We apply the 1+1+2 covariant approach to describe a general static and
spherically symmetric relativistic stellar object which contains two
interacting fluids. We then use the 1+1+2 equations to derive the corresponding
Tolman-Oppenheimer-Volkoff (TOV) equations in covariant form in the isotropic,
non-interacting case. These equations are used to obtain new exact solutions by
means of direct resolution and reconstruction techniques. Finally, we show that
the generating theorem known for the single fluid case can also be used to
obtain two-fluid solutions from single fluid ones.
