what is seafan?

[m12345y]

what exactly is sea fan, the entire tree-like thing or just the blue-ish surface layer (for bali seafan)?

[albinosage]

The entire branch is the skeleton of the coral, covered with tissue, and the "surface area", I assume it's the polyps you are referring to. They feed by using the fan like structure to filter the current, catching plankton with its polyps.

thanks, then should i cut away those branches without polys?

I don't think you should do that if the flesh is still visible, cos the polyps might just be closed or retracted. If the branch without polyps is totally bare skeleton, as in, wire-like without flesh, I don't see why not. But bear in mind that if too much skeleton is exposed, that means it is probably not doing well and dying already.
