Questions about coral

[Kenny's reef]

Does my coral look healthy please be honest
An why dose my Rasta zoa look like that?

 

[Fink]

The favia and the xenia look fine.

The hammer isn't fully open, but that could be from a number of reasons, usually for me hammers don't fully open the first week or so in a new tank, or if the flow is too high.

For the zoas mine sometimes did that in the first year that the tank was setup for seemingly no reason at all, but they don't do it much anymore, so I don't really have an answer... I didn't move them or anything to get them to open fully... they just decided to do it one daay.
