I have an acan that is growing heads that hang off the rock it is on. What is the best way to handle this. Should I just place a rock or plug there and if I do will it attach. Or ??
I never had this before but now with my LED lights my corals are growing.
It shouldn't attach unless you glue it to a piece of rock. They precipitate a calcareous skeleton with which their tissue attaches. They do not produce a stolen like a star polyp or Zoanthid does enabling it to adhere to anything next to it. Nor is it an encrusting coral like Montipora Nodosa, Verrucosa or some species of Porites and Millipora.
Place it in the sand and it will grow flat as mentioned above.
