There are currently so many dark energy scenarios, each leading to a different phenomenology, that it will be hard to compare their predictions with the observations of future surveys. I will review a unifying approach to describe dark energy and modified gravity models based on a single scalar field and allowing different matter species to couple differently to the gravitational sector. Restricting to the quasi-static approximation, I will discuss the constraining power of a future redshift survey with Euclid-like characteristics on the parameters of such description, in the case when cold dark matter is non-trivially coupled to the gravitational sector.
