We prove that every non-elementary hyperbolic group G acts with maximal growth on some set X such that every orbit of any element g ∈ G is finite. As a side-product of our approach we prove that if G is non-elementary hyperbolic, \HH ≤ G is quasiconvex of infinite index then there exists g ∈ G such that <\HH,g> is quasiconvex of infinite index and is isomorphic to \HH*<g > if and only if \HH ∩ E(G)= \e\ , where E(G) is the maximal finite normal subgroup of G.
