I'm pretty sure this is a Hollywood Stunner chalice but not 100%. Its a very nice specimen but very very thin and brittle compared to most chalices I've seen. I chipped a very tiny piece of the edge handling it. Pics are poor but its mostly a blue purple with green spots here and there. I have a 120w led fixture over my 39 gallon tank. Should IR be placed close to the light of towards the bottom and what to fees this piece? Thanks this is my first chalice.
