In my search for live mysis for cuttle food found this place out of Fort Collins. More setup for science insitutions, seemed a little hesitant to my questions, have minimum order sizes and much and don't have a public front. (But for now said I could probably pick up orders there)

They have live mysis but besides that I saw they have live rotifers and Marine Amphipod (Leptocheirus plumulosus), which I dont know if would be good seeders for rock or food.
