Neolamprologus sexfasciatus ( synonym : Lamprologus sexfasciatus ) is in the southern half of the East African Lake Tanganyika endemic occurring cichlid .
description
When fully grown, the fish reach a length of 14 to 15 cm, have a silvery-white, gray-white or light-blue basic color on which six black or dark blue cross bars can be seen. The first transverse band is over the gill flaps, four are below the dorsal fin, and the last is over the caudal fin stalk. This makes Neolamprologus sexfasciatus very similar to Neolamprologus tretocephalus , which lives in the northern half of the lake. However, this species only has five transverse bars, three of which are below the dorsal fin. A morph of Neolamprologus sexfasciatus found near Kipili on the Tanzanian shore of the lake has a lemon-yellow basic color and pale, light-bluish transverse bands. The teeth on the posterior section and in the middle of the pharyngealia of Neolamprologus sexfasciatus are flat and molar-shaped and thus adapted to the biting of molluscs . There is a conspicuous blue iridescent spot on the gill cover .
- Fins formula : dorsal XVII – XIX / 27–29, anal V-VII /?
- Scale formula : 34–37 (mLR)
- Gill rake : 11–13.
Habitat and way of life
Neolamprologus sexfasciatus lives close to the shore in very shallow water at depths of 2 to 5 meters in the rock and scree zone of the lake and carnivorously feeds on small snails ( Neothauma and others). The fish are cave breeders . Eggs, larvae and fry are cared for and defended by both parents. After swimming freely, the fry do not form a school, but remain true to their location in their parents' territory until they have reached a length of two centimeters.
