I found this on the front of my tank. Is it coral larvae? I have pipe coral and red mushroom coral, and probably a million other things that came in on my live rock. I guess it didn't like the sand being stirred up, and I found it on the glass. Should I move it? Will it latch there are grow? I would rather it chose a rock, but I don't want to kill it. I have never had coral before. Please help me not murder them.
