**FILE** Fish of the species symphisodon eaquifasiata (discus) originate from the Amazon River and the Rio Negro, and are members of the Cichlids Family. They feed their offspring through bodily secretions that enable them to live in habitats lacking in food for the offspring. Photo taken at Dansiger Discus Farm at Mishmar Hashivah, Israel.
