Zoanthid for substrate?

[007]

I am in the planning phase of my new up and coming SPS reef and have decided to go with a remote sandbed in the fuge.
The display tank is going to be a starboard bottom, and the thought crossed my mind to glue some zoanthids on the bottom and let em spread along the starboard.
What problems do you all see in doing this?
The first one that comes to my mind is the zoo's spreading up the rockwork, but I think that would be easy enough to control.
What else?

"Might" disrupt flow and allow detrius to collect...Which 'could" be harder to siphon out with the zos "stuck" to the bottom..?

well, since it would be an sps reef there is going to be LOTS of flow, hopefully enough to keep detritus in suspension and removed via the skimmer.
I see your point though, but I could just as easily cause the polyps to close up and siphon around them if needed.
