I purchased a small blasto frag a month ago which appears to be doing well. The frag originally had three small polyps attached to a golf ball sized piece of rubble, but now has three large and three small heads. My question is this, I tried to move the blasto yesturday, however the minute that I moved it, the blasto stalks detached from the rubble. When I purchaed the blasto, the stalks were well attached. I placed the stalks on a large piece of live rock, and it appears none the worse for wear. Should I be concerned? My calcium level is usually around 400-425.
