during one of my frequent forensic level observations of my tank (I'm surprised I don't need to wipe nose prints off my tank!) I noticed this little fella...
Bubble anenome? Coral? If you look close he actualy has a few siblings. This is on a rock that has been in my tank for over a year. The only recent additions to my tank are Chromis, Yellow Tang and a small rock with mushrooms (which are budding!
Any ideas what this might be? oh... it's only about 1/8-3/16ths of an inch in diameter... (i'm gettin good at these macro shots!)
