Sera has brought out a new, natural food for ornamental fish called sera Nature. The food contains only natural ingredients and has no colourings or preservatives. The six varieties in the Nature line include Vipan Nature and Goldy Nature. These each use insect meal from the black soldier fly as a high-grade, sustainable protein source for the first time, in addition to fish meal from sustainable fishing. Four tablet foods and a breeding food will shortly be added to the Nature line. www.sera.de
