Original description as Tropheus annectens:
- Boulenger, George Albert. 1899. "Matériaux pour la faune du Congo. Poissons nouveaux du Congo. Cinquième Partie. Cyprins, Silures, Cyprinodontes, Acanthoptérygiens". Annales du Musée du Congo Belge. Zoologique 1; p 122 (crc00130)
- Tropheus polli Axelrod, 1977, with type locality at South of Bulu Island, Kigoma District, Lake Tanganyika, Tanzania. Determiner: Konings, 1992
Conservation: Tropheus annectens is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (LC) least concern (2006). Apart perhaps from the shallow rocky reefs near Kalemie (Congo) the habitat of Tropheus annectens is not threatened by siltation or other destructive human activities. The species is not caught by local fishermen as they are too small and too difficult to collect as they live among rocks.
