I usualy prefer live rock or rubble.
However I had actualy seen some plugs that looked fairly natural. They were basicly mushroom shaped like a 3/4" ball cut in halt with a small stem comming out of the bottom. rather than the flat top with a hole in the center type you commonly see. Now for zoo's I think these mushroom shapes would be ideal however if your into SPS's they mah not be ideal.
