Best for Corals for bioluminescence / fluorescence

[rbjohnston]

One of my favorite things in my tank I had years ago was how certain corals would glow at night. I could stay up for an hour admiring the colors and the night life that would come out. I had mostly zoanthids then. What are some of the corals that you all love that put off that beautiful glow at night?
