I hope I am not giving misinformation about this Yosemite Sam. Thanks for the correction earlier. I have never been able to find a lot of information on these, I am pretty sure they are from the Caryophylliidae family, Paracyathus Stearnsi or Balanophyllia Elegans, similar to a sun coral or a dendro. Most that I have seen have been either clear or brownish in color. They are more like a solitary hard coral than an anenome(don't know why they are called this sometimes).No real special care, they will catch food with their tenticles, I don't think they contain zooxanthellae(not sure on this), so they should be fed zooplankton and meaty type foods if you want them to thrive, not just hang on. Again, never found anything "concrete" about these little guys, I guess I will keep searching for more information on these. I wish I had them in my current tank, have had them years ago, gave the rocks to a friend before we moved.
