New coral tank

[Rakkasan]

Hey everyone I am new to the hobby but I am retired and do a ton of reading and research however I am lacking in my coral knowledge but I will get it down soon.

Please provide some guidance and or suggestions for my tank. I will attach pictures for your punishment.

My main question is for my Duncan which wasnt doing very well up top so I moved him into the shade and still didnt look good. Now that I moved him again he blew up and fully bloomed but he looks like he is bloated and going to explode.

Please let me know your thoughts. I used just white light for the photos which makes them look like ****.

Things overall look pretty good. As far as the duncan was most likely do to change in flow.
