I feed my fish different mixtures of Mysis, Rods Reef Food, Dry Hatchery Diet, and Formula 2 Flakes. I can obviously put the Dry Hatchery and Formula 2 in the auto feeder, but they just float and end up in the overflow and not eaten. I normally soak them first to make them sink a bit. I obviously cant do this with an auto feeder. What food would you recommend? Will be gone for a week.
