Went to my LFS today and he gave me a free montipora digitata frag. It looked fine in his tank from the side i could see it. When i got home and put it in the tank i noticed some white on the side that i didnt get to take a look at in my LFS tank. So i just want to know if its bleaching or growing? If it is bleaching, anything i can do? Let it be, frag it or what? Its my first experience with SPS. Thanks for any help Marc.
