Vermuelen Frans Vermuelen Frans Vermeulen was born and raised in The Netherlands. As a child his fascination with all types of aquatic life was almost an obsession. As a young adult Frans became so addicted to the aquarium hobby that he made it his daily profession and opened an aquarium shop that soon became widely known throughout The Netherlands and the neighboring countries. While raising a family he kept the business growing for 15 years, and then at the age of 50 he closed the business, and together with his wife Marjan, he moved to the sunny island of Aruba in the Caribbean. His passion for killies continues and has become a way of life for him. Today his fish room contians about 250 small aquariums in which he keeps and breeds many species of killies, but only the ones from South America. Frans has made numerous expeditions to various parts of South America like Argentina, Guyana, Surinam, Venezuela and Colombia, and he readily shares his experiences as speaker at international killifish conventions in Europe, South America and the USA. He has described some new species and is now working on several new species that he discovered himself not long ago. Frans has also written numerous articles for fish hobby magazines about his fascination. In addition he maintains a multifaceted web site which is a "must see" for all who love killies from Middle- and South America in particular
