The success story of sera began over five decades ago: Josef Ravnak, who already had gained an excellent reputation with the selling of live food for aquariums, founded his own company in 1970. He first worked as a one man enterprise and developed the company into a leading supplier within the aquarium, pond and terrarium industry, step by step. Sera ensures the quality of the extensive range by adhering to the strict regulations of Good Manufacturing Practice (GMP). These regulations are acknowledged worldwide. Please note that some sera products displayed on their website may not yet be available in Australia, or are not available due to regulatory requirements or marketing reasons. The item images represent some of the most popular items in the extensive sera product range available in Australia. All sera foods are described as “Nature” foods due to the inclusion of insect ingredients as a sustainable protein source, thereby reducing the reliance on fish meal.
