The coral/anenome in question is about the size of a dime, it was on the rock when I bought it. It has tenacles, but they are very tiny with a slight bulb on the tip. I have seen it eating before, kind of curled up around whatever it caught. If you look to the left of it, there is some sort of colony of them, or something very similar. I am suprised any of them made it. I had a mantis in that rock, and it got the old fresh water dip, probably not the best thing for that rock, but the mantis is now gone, and all life on the rock seems to have recovered.
Again, I appreciate all the info, I am new to saltwater, I have a 75 gallon set up for about 8 months (getting the itch to convert my 150), and this website is one of the best resources for information that I have found. Thanks for all the help.
