sps... feeding?

[GMGQ]

I agree. Food sticks to the polyps because cells on the polyps contract or whatever to make them sticky, then they retract into the skeleton to 'eat' it.

So in the mildest definition of "prey" I would agree that they do.

so yes, SPS do catch food and therefore are predators.

If sps polyp extention, especially at night, is for purposes other than eating I would be interested to know what those actually are. Since I have a mixed reef I need to feed my Gorgonians, LPS and Clams etc. anyway, so if the sps want eat it's they can. I feel it's sort of like chicken soup for a cold, may not help but it won't hurt.
