new coral.

I'm no expert but don't they prefer less light??

isn't that a sun coral?

they look like suncoral. if thats what it is, suncoral is non photosynthetic so the dont really care eitherway just make sure you feed each individual head everyother day with something like frozen mysis

ditto ^ *IME* for suncoral, its not that they don't like light, its they don't need light.

Either sun coral or the "dendro" that everyone seems to be getting. They don't give a crap about light. It doesn't make any difference if you put one at the top under MH or at the bottom under PC. Just keep 'em fed.
