If you plan on fishing the Blue, Taylor, or Frying Pan tailwaters here in Colorado, then you will want to have a fair amount of Reid’s Ultra Mysis Shrimp stocked in your box. Large fish in these tailwaters feed on mysis shrimp almost too exclusion. Actually, one could say that trout feed on mysis to get large. Trout steroids. You will know these fish by the pink hues of their sides (yes even brown trout who feed on these critters develop a slight pink coloration).
