So after listening to Tony talk about plate corals, it got me to doing a lot of research on the topic, Even more than I did when I purchased it about a month ago, I have a short polyp orange plate. I have it sitting on sand in a medium flow area, It has the prettiest colors to it, a bright orange trimmed in a beautiful purple with a tiny bit of green going through it. I do see it open just a tad during feeding, but that is the only time I ever see it move and its not at every feeding. It has never inflated, its real thin, and never moved an inch from where I placed it, Is that normal?
