Coral Frenzy, Cyclopeeze and occasionally brine shrimp. I notice an immediate response from every coral in my tank when I feed Coral Frenzy. Hmmm, maybe not the zoanthids or Xenia. But all my SPS and LPS. In fact, yesterday morning, about an hour before actinics came on, I fed Coral Frenzy. When actinics came on, I noticed more expansion and tentacles on my Candy Cane than I'd ever seen before. All of my SPS were fully expanded as well!!
