I do have the frozen cubes, Krill, Mysis, brine Shrimp and the formula One cube. I also soak it on Selcon once in a while. Which one is the most beneficial in terms of fish health? The reason that I want to try the dry foods is for the automatic feeder when I'm gone on the weekends and also want to alternate it with the frozen every other day. It seems that the Spectrum Thera A and the cyclop-eeze will be a great choice.
