The Luhanga population

It is the same species as Julidochromis transcriptus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Julidochromis transcriptus, the masked julie, is a tiny rock-dwelling cichlid endemic to a short stretch of the northwest shore of Lake Tanganyika. Boldly marbled in black and white, it is one of the most popular dwarf "julies" in the aquarium hobby — a hardy, cave-spawning fish that pairs for life and tends its young in a rock crevice. Yet that same desirability is now its undoing in the wild: with a known range of barely 37 km², it was uplisted from Least Concern to Critically Endangered in 2025, driven almost entirely by collection for the ornamental trade.
