So far so good... the only corals I'm not sure that are getting the roids are the SPS, but who knows. My zoos, ricordia, BTA, LPS all of them love it. The yuma, ricordia and anemone are the most interesting to watch eat it. The anemone loves it, the yuma starts to look pretty rad after 5 minutes or so while it's eating it.

Two thumbs up from me.
