Ruby Green Haplochromis

Haplochromis sp. 'Ruby Green'

Ruby Green is an undescribed Kyoga-system cichlid recorded from varied lakes and even flowing water; each captive line still deserves precise provenance.

Ruby Green Haplochromis: A Jewel-Colored Line From Uganda's Kyoga System

An undescribed haplochromine whose ruby-green males occur across varied Kyoga-system habitats, with ecology that can differ by locality.

Published by Crystal Springs Fisheries, Inc., d/b/a LiveFishDirect ©2026

A species still waiting for a formal name

Ruby Green is recognizable enough to have been bred and traded for years, yet it has not been tied to a published species description. That is common among the haplochromines of the Victoria and Kyoga systems, where enormous diversity, rapid ecological change, and incomplete museum sampling have left many lineages under working names.

The product should keep the "sp." visible. It signals that the line is real but the formal taxonomic boundaries remain open.

One lineage across varied Kyoga habitats

Recent field reporting places Ruby Green broadly across the Lake Kyoga system—in shallow and larger lakes, clear and turbid water, and flowing Nile habitat. A Nawampasa population has been observed grazing epiphytes from aquatic plants, but that local ecology should not be turned into a rule for every population.

This broader range does not make every locality secure. Kyoga-system waters face invasive species, shoreline change, eutrophication, aquatic-plant disturbance, and altered connections, with different effects from place to place.

Reports have raised concern about possible local disappearance at Lake Nawampasa, while the fish has also been reported elsewhere in the Kyoga system. IUCN has not formally evaluated this provisional taxon, so the page should state uncertainty rather than declare either extinction or security.

Male color as a developed condition

The ruby-green display belongs primarily to mature males. Females and juveniles are quieter, and subordinate males may retain bars without the full upper-body fire.

That makes a young Ruby Green a fish of potential rather than a miniature copy of the hero image. Farm photography should show more than one stage so customers understand the transformation.

Captive lines as living records

For an undescribed fish from a varied and changing regional system, a carefully maintained captive line has two forms of value. It supplies aquarists without wild collection, and it preserves a lineage that may become scientifically important as field populations are reassessed.

The line must remain separate. A colorful hybrid may be attractive, but it cannot substitute for the original Ruby Green identity once the provenance is lost.

At Live Fish Direct, the work of raising fry becomes a form of archive keeping. Each generation carries color, behavior, and ancestry forward while the scientific name and wild status remain unsettled.

Ruby Green is beautiful because the colors meet. It is important because the habitats and records behind those colors can come apart.

Common questions

Ruby Green Haplochromis FAQ

Clear answers to common questions about this fish.

Is Ruby Green Haplochromis a described species?

No. It remains under the provisional name Haplochromis sp. 'Ruby Green.'

Where does it come from?

The fish has been reported across the Lake Kyoga system, including Lake Nawampasa and varied lake and river habitats. The exact farm-line locality should be tied to breeder records.

Do females show ruby and green color?

The strongest display is usually a mature male trait. Females and juveniles are more subdued.

Why does captive breeding matter?

It can preserve a correctly identified lineage while its formal taxonomy, field distribution, and individual population histories continue to be clarified.
