I set up my first tank last Thursday (11/3) with some live rock and dry sand. The day I noticed a purple blob attached to one of the rocks. i decided to let it be and see what happens. Today when I woke up it looked like this. Do you guys know what it is? Should I keep it or pull it off before it becomes a problem?
