ok so i have been feeding my pictus cats this sinking shrimp pellets and then put extra tetra flakes when feeding so some of it falls to bottom and extra treats (insects) i put in sometimes for the fish that goes to the bottom, the pellets are now almost empty so i wanted to get your guys opinion on a good food to feed them for the main part of their diet as im not sure if these pellets are supposed to be fed as a staple (i think they are wardley shrimp pellets but not sure)
