I have a Montipora Capricornus SPS coral frag in my new reef tank, all my levels seem to be doing well, but this frag is noticeably less vivid than it was in the store and the first day. What should I be feeding it? So far, all corals have been filter-feeding very nicely except this one. I am looking into the Kent brand invert feeders at my LFS. Does anyone have any insight into whether it may be dead or how to tell?
