Congo supplies wild fish from rivers and some small lakes (here no fish from Lake Tanganyika). Only wild fish are available and therefore shipment preparations need more time.
Some of the fish can become very large and have therefore large interest for the Asian market and the public aquaria.
Only a few exporters are active since it is political, technical and financial difficult to run an export facility.
The most common fish available are Synodontis and other catfish, Polypterus, Congo Tetras, Distichodus, Tiger fish, River Cichlids, Mormyrids, Puffer Tetraodon, etc.
