Identify some corals for me please

[carriej]

I'm sure these are easy corals - I just am new at this. I picked up some frags for a very good price from a hobbyist so maybe I was a bit out of line picking up things I weren't quite sure of - but I decided to take advantage of the situation.

I *think* I was told favia. However someone told me it was an acan. I can't tell the difference. It shrinks at night and swells during the day if that helps. It doesn't necessarily matter to me what it is - I like it



Candycane? I have a candycane.. It looks like it, but sorta not in the same sense...
