My tank has been up and running about 6 months or so now and it's almost entirely SPS and zoas.  The zoas are really spreading now and soon will be very close to some SPS's.  Will I run into issues once the zoas get to the SPS's, or will they just form a blanket around the bases of the SPS?  THanks.
