I recommended Otohime here on MFK in the past, for those looking for a less cost feed alternative that could be purchased in bulk. Having said that, once you get into the larger pellet sizes the formula changes, and IMO doesn't look any different than any other starch filled pellet. Wheat-Tapioca-Corn-Potato-Soy, more Wheat.
EP 8-10 mm Otohime pellets
Fish Meal, Wheat Flour, Tapioca Starch, Corn Starch, Potato Starch, Fish Oil, Calcium Phosphate, Soy Meal, Wheat Germ.
Far better feed options available here in North America, than that starch filled food.
