On this page of our website we propose to test the knowledge of fish species in the form of a riddle. During the year 12 times we will present a picture of a fish autochthonuos in the Caprathian basin the species which should be identified. We ask the participants to send the following data: name, country, city and the name of the species according to Fishbase or Fish Fauna of Hungary book.
   Following every round we will publish the proper answer.
