Supermassive black holes at high redshift (z>6) with masses as large as those in our local Universe are now abundantly observed in large-scale surveys. This questions our understanding of black hole growth in the first Gyrs of cosmological evolution, and how 10^9 Msun of gas can be trapped at the heart of primordial galaxies. I will show how cosmological hydrodynamical simulations can help to design a scenario for feeding those massive beasts, and what problems arise when one wants to take into account the spin of BHs in the global picture.
