A bought a container of NLS Color enhancing, 3mm sinking pellet in the Large Fish Formula about a year ago. I think it is lot # 102, and I forget the expiration date.
Ingredient list: Whole Antartic Krill, whole fish, whole wheat flour, ulva seaweed, chorella algae, Beta carotene, kelp, spirulina, garlic, alfalfa, mollusk, and the list goes on.
I bought a newer container of the same pellet about a month ago. I think this is lot #103 and expires in 2018.
Ingredient list: Whole Antartic krill, whole fish, whole wheat, ulva seaweed, chlorella algae, Beta carotene, spirulina, kelp, garlic, alfalfa, scallops, and the list goes on.
Seems to be about the same except for a switch in the amount of spirulina algae vs kelp, and mollusk vs scallop.
