These look much like other sinking shrimp based pellets but unfortunately they were not well received by my fush (Corys included)
Ill just spend the little bit extra to get a better brand next time.
Well then they seem to work quite well!!!! and for the fish tank and the fish pond!! great for the fish tank as the fish seem to bottom feed and clean the bottom structure better than hanging around the surface!!! Result is a cleaner fish tank!!!
