The six-banded distichodus or sixbar distichodus (Distichodus sexfasciatus) is an African species of freshwater fish in the family Distichodontidae. [2]
Distichodus sexfasciatus can reach a length of 76 cm (30 in). The body is high-backed, reddish brown to reddish-yellow colored, with an elongated, partially squat and laterally flattened head and six dark vertical bands. Its snout has a characteristic conical shape. They have 24–25 dorsal soft rays and 14–15 anal soft rays. [2] [3] These fishes feed on worms, crustaceans, insects and plant matter. [2]
This species can be found in Africa, in the basin of the Congo River and in the Lake Tanganyika in the Democratic Republic of the Congo, Central African Republic, Zambia and Angola. [2] [1] These freshwater fish occur in swarms and schools in rivers and lakes, in areas of tropical climate (typically 22–26 °C or 72–79 °F). [2]
Lake Tanganyika is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.

Takifugu obscurus or the obscure pufferfish is a species of euryhaline, anadromous pufferfish first described by T. Abe in 1949. It has been categorized by the IUCN as a least-concern species globally since 2014; in South Korea, it is however classified as an endangered species due to overfishing of its endemic populations. The Catalogue of Life lists no subspecies of Takifugu obscurus. The species prefers deeper, clearer areas of brackish and fresh water, and is found in estuaries, as well as rivers and tributaries thereof such as the South Korean rivers Geum, Han, and Imjin, or the Tamsui River in mainland China. The species is endemic to North and South Korea, the Sea of Japan, and the East and South China Seas. Uses of Takifugu obscurus include human consumption, use in animal testing, and owning specimens as pets. As with most species of pufferfish, several organs of Takifugu obscurus contain tetrodotoxin, making it potentially poisonous if not prepared safely by trained persons.
