I love coral frenzy. For my tank, never saw corals go after any other non frozen food, compared to this product. My only problem, is this stuff is very expensive.
An interesting product I have used is Marc Weiss Reef bugs. It is stored in refrigerator in a nice sized baggy. Does not look like much, however, I would use a 1/8 to 1/4 teaspoon daily and corals loved it. Supposedly it come "alive" in tank. Never saw anything alive, however, the lps's loved it.
