A week ago i picked this closed brain frag for cheap ftom my LFS as my first coral. Is the skeleton supposed to be showing like this? If not, what do I need to do? One side is starting to develop some algae on it which is concerning me, and I can't find any frags that look like this online to see if its normal.
