Walteri
Neolamprologus marunguensis
A deep-water Tanganyikan shell-dweller with a deeply forked tail and fascinating family dynamics.

About
Found along both the eastern and western rocky shorelines of Lake Tanganyika, Neolamprologus marunguensis is a small cichlid that lives at considerable depth in its natural habitat, picking its way through boulder-strewn zones well below the surface. It was traded for some time under the informal name Neolamprologus sp. "walteri" before receiving a proper identity, and it remains less commonly available than many of its Tanganyikan relatives. One of the first things you notice is the distinctly forked tail, which sets it apart from a lot of the compact Neolamprologus species that share similar rocky terrain. Despite a reputation for aggression on paper, this fish is actually fairly tolerant outside of spawning situations, where it defends its cave and surrounding territory with real conviction. A species-only setup is the safest approach, though a roomy tank can accommodate other Tanganyikans that occupy different water columns, like open-water Cyprichromis, or rockdwellers such as Julidochromis if space and territory allow. Breeding is genuinely straightforward. Cave spawning pairs raise multiple generations together, with older siblings often allowed to remain with the parents, creating a layered family group that is rewarding to watch. This makes it an appealing choice for anyone stepping into Tanganyikan cichlids for the first time.
