Faux-Reef?

As my tank is cycling, I`m pondering the the thought of a kind of Faux-Reef
set-up. Not the plastic stuff!!

Im thinking of having inverts that are not that expensive or are relatively
easy to keep. (IE NOT Corals or anenomes!)

For instance: Feather Dusters----are there different varieties of these?
Also Gorgonians---but they seemed to die off pretty quick back in my
undergravel filter days in the 80`s.
I also had a tube anemone back then did great without any special lighting.
Can anyone suggest other mostly sessile type inverts that might do well in a
FOWLR tank with generic lighting?
Plants are cool too,

thanks
