Tropheus polli

Tropheus polli is a species of cichlid endemic to Lake Tanganyika, where it is only known from the central eastern portion of the coast in areas with rocky substrates. This species can reach a total length of 16.5 cm (6.5 in). It can also be found in the aquarium trade. [1] The specific name honours the ichthyologist Max Poll. It is considered by some authorities to be a synonym of Tropheus annectens . [2]

Cichlid Family of fishes

Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, Labroidei, along with the wrasses (Labridae), in the order Perciformes but molecular studies have contradicted this grouping. The closest living relatives of cichlids are probably the convict blennies and both families are classified in the 5th edition of Fishes of the World as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000.

Endemism ecological state of being unique to a defined geographic location or habitat

Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species that are restricted to a defined geographical area.

Lake Tanganyika lake in Africa

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 divided among four countries – Tanzania, Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. The water flows into the Congo River system and ultimately into the Atlantic Ocean.

<i>Tropheus</i> genus of fishes

Tropheus is a small genus of six species of cichlids endemic to Lake Tanganyika in East Africa. The genus is widespread across all regions of Lake Tanganyika, from Burundi in the north to Zambia in the south. Males and females are relatively similar, but do display obvious sexual dimorphism. Males attain a somewhat larger size. All species maternally mouthbrood their eggs and fry, and this characteristic provides their generic name. Tropheus comes from the Greek trophos, which means "to nurse" or, according to Boulenger, "one who rears, brings up, educates". The genus is fished lightly by the local population, but has never become a staple food fish due to its relatively small size and its habitat, which enables it to dart between rocks when threatened.

Mesonauta, the flag cichlids, is a small genus of cichlids native to the Amazon, Orinoco, Essequibo, Paraná and Paraguay basins in South America. Mesonauta is included in the subfamily Cichlasomatinae. They occur in various freshwater habitats such as streams and lakes, especially in areas with little water movement and aquatic vegetation. They are generally found in small groups that stay near the water surface. To avoid predators, adults may jump out of the water and juveniles mimic leaves.

<i>Microsynodontis</i> genus of fishes

Microsynodontis is a genus of upside-down catfishes native to freshwater rivers in western Africa. The genus was originally described by British-Belgian zoologist George Albert Boulenger in 1903 based upon the type species Microsynodontis batesii. The name microsynodontis comes from the Greek word mikro, meaning small, and the Greek term synodon, meaning "with the teeth all growing together".

Shrimp mix, also known as European shrimp mix, is a frozen fish feed used for fish with special dietary requirements, e.g. Tropheus, which are difficult to maintain using normal fish feed. The basic version is intended for herbivorous fish and is made by blending equal amounts of whole shrimp and green peas to a smooth paste, adding a vitamin supplement, and using either agar-agar or gelatin as binder. There are numerous variants tailored to the specific needs of different species. Common variants replace part of the shrimp or peas with fish meat, spinach, spirulina, or mussel meat, and add astaxanthin, ascorbic acid, or garlic.
