Yes, provided the fixed point is attracting and positive real.

i believe we need oo to be repelling and f^^n(z) converging for lim n-> oo and any z too.

You mean , right? For "any" z seems too restrictive: , for example, does have many -values for which its iteration diverges, but these do not show up in the range of the tetrational .
