Somehow, I have accumulated over the last couple years about 40 chalices in my sps dominant tank. I mean what else are you going to place on the lower third of your reef scape.
All of mine have been around for a while and were pretty inexpensive (at least for a chalice). I work all over Los Angeles and so when I can, I try to drop by lots of different LFS. If you are patient and time it right, there are some beauties to pick up really cheap. Also have gotten some great deals with local hobbyists as well. Most of these started out as about dime size pieces and some larger. Patience is a wonderful attribute in this hobby--wish I had more of it
One of my many favorites
