Thier perfered method (best method of capture using less energy) is throught the use of a mucus slime that nets its prey, be it bacteria or zooplankton. the net is drawn throught the polyp via the cilca (sp), and the coral injests it thier. As per energ budjets for hermatypic corals I have also read alot including sorkin and most of the other Boomer mentioned above. But I have never seen any study that should a SPS had a supplimental food supply requirement above 10%????

I totally agree
I was just trying to lead some people to papers showing that you can't lump all corals into one category regarding feeding. Some get all their energy requirements from feeding, some probabbly get all they need from zooxanthellae.
I believe I read Borneman (this isn't a citation, so I could be wrong
) that symbiotic algae could possibly provide up to 110% of a corals energy needs...
Anyhow, I think somewhere in the process this thread has strayed from Scott's original intent
