The discus isn’t picky when it comes to the style of fish food they will accept. Equipped with grinders in their jaws instead of teeth, the discus eats by breaking down food, spitting it out, and recapturing it to swallow. This process allows particles to fall to the bottom of the tank, where the fish can shoot water at the food and then grab their morsels as they float up. Some will even do this on purpose, as a little game, and spend up to an hour after a main feeding searching for and cleaning up leftovers. Regardless of whether you’re using floating flakes or sinking pellets, the discus will eat.
