Out of curiosity would you say your lead product is the frozen mysis or something else? I've personally used the frozen and recently pellets. Frozen is great of course without any debate but I was more surprised by the pellets as ALL my fish eat that eagerly. A different popular brand of the same size only 2/3rds of my fish would eat. I would also say your pellets smell like the frozen (nasty) which I take to be good thing. The other smells more like... cat food, and strikes me as more 'processed'.
