I haven't tried the frozen, but did get the whole freeze dried that you are asking about.
At the moment I only have a couple of corals, a cleaner shrimp and a bunch of different snails. I wet my pinky and put it in the container then in the tank. All the snails reach out into the once it is waterborne (really neat to watch), the cleaner comes running out of the rock work- I can't say for sure what the corals are doing since they use the lights also as food...(a torch, and toadstool)
I would say it should work just the same.
