A pretty piece that will change color depending on lighting.  I like placing this piece on non-flat surfaces in display tanks as the darker areas will appear bright green while the more well lit areas will be yellow.  The polyps are pink which provides a nice contrast in coloration.
 
Frags will be ~1/2" - 3/4" -  Pics are for representation of the coral only.  Frags of the coral are very similar but not exactly as seen in the photo.  Please visit our WYSISYG section if you want to purchase exactly pictured corals.
