Lake Tanganyika, the longest lake in the world (660km), is one of the best kept secrets and one of the most beautiful places to visit in Tanzania. This incredible rift lake is home to biological diversity hotspot with over 2,000 species of plants, fish, birds and invertebrates that are only found in this part of the world. But the one animal that steals the show is the cichlids (home aquarium fish). There are over 250 types of cichlids, each more colorful and more beautiful than the next. Most species of cichlids are specialized feeders so many different types can live together without too much competition, allowing visitors to see all kinds of cichlids on their visit. The best way to see these colorful creatures is, of course, through a scuba diving adventure.
The second deepest lake in the world (1,436m), Lake Tanganyika was formed when two tectonic plates move apart from on another to form a divergent boundary. Since this divergent boundary was formed between two continental plates, a rift valley was created. Great amounts of water collected at the bottom to create a rare type of lake: a rift lake. Lake Tanganyika is one of the oldest lakes, estimated to be between 9 and 13 million years old. Today, Lake Tanganyika supports one of the largest fisheries with approximately 100,000 fishermen at 800 different sites working along the lake.
