Here is my advice. Don't worry about it too much. I did the same thing when I got my first coral, it looked unhappy and I wanted to fix the problem. Sometimes trying the too hard to fix a problem can create others. Try to get your tank on a normal schedule (lighting, feeding, water changes...ect.). As long as your tank is cycled properly and your lighting/filteration is adequate, there isn't much you can do. Keep up with your water testing: pH ammonia nitrate and nitrite.
You may want to check your pH at night and early in the morning to see if you are getting a pH swing.
I would not add any more livestock until it starts to stretch out and looks comfortable.
