Candy Cane Coral Browning

Hey i recently purchased a candy cane coral and now its turning browner and browner every day. I tested my water and everything is good. My hammer/frogspawn (dont know what it is) is doing well as well as my zoas. The last few days my flower pot coral hasnt been fully expanding also.
