A beautiful chalice if you like Chalices.  This Chalice is in the Mycedium Family and grows at a good rate.  Low Lighting is a must, they will not tolerate any high lighting.  Bottom of the is a good placement.  We light to cut a piece of PVC pipe to put under the coral if you have substrate in your tank.  This will stop sand blowing on top of it or fish digging and burrying the coral.
