How to Feed

Drop one or two pieces into the aquarium near your shrimp, snails, or plecos, mixing colors for variety. Because the pieces do not dissolve, you can leave them in for grazing and simply remove any uneaten portion after a day to keep the water clean. Feed a few times per week alongside your staple foods.
