corals that have sweepers?

What sorts of corals have extra feeders that come out only at night? I know candy canes do: about the length of the head tissue and clear, anemone-like. Brains do, don't they, little ones around the ridges? What else has sweepers at night? Anybody have pictures of same?
 
Here's a picture of my Cynarina fedding.

I finally got a fuzzy pic of my candy cane at night. It's not at quite full extension, but you get the idea. I love how the tank changes from daylight to dark.

Most LPS put out feeder tentacles at night. Galaxea and Diploastrea can put out some long nasty sweepers both day and night. Acanthastrea, favia, platygyra, echinophyllia, lithophylon, caulastrea, goniastrea, etc... all usually have feeders out at night.
 
I was surprised to find that even pocillipora, my innocent little sps bird's nest, is apparently capable of inch long sweepers. No hint of this yet, though it's growing. The ac. cerealis has some about a quarter of an inch long. The yongei just gets hairier, if possible. Here's the cerealis. I don't know if it shows, but it just grew a ring around its base and those feeders are starting to come out, probably preparatory to having other branches. This frag is about 2-3 months old.
