Taxonomy & naming
Cynotilapia sp. "Lion Chinyankwazi" has never been formally described, has no describing author or publication date, and does not appear under a validated name in Eschmeyer's Catalog of Fishes. The qualifier "Lion" conventionally denotes a gold-to-orange body coloration in Malawi mbuna trade nomenclature, a naming pattern used for comparably toned colour forms in several other genera; it distinguishes this population from the blue, black-vertical-barred Cynotilapia sp. "Chinyankwazi" documented from the same island, whose pattern is close enough to Maylandia (formerly Pseudotropheus) zebra that Ad Konings has noted the resemblance directly. Chinyankwazi Island and its neighbour Chinyamwezi are recorded in Konings' Cichlids Yearbook series as falling within a protected area of the lake where ornamental-fish collection is forbidden. Whether "Lion Chinyankwazi" is a distinct lineage from the blue Chinyankwazi form or a colour variant within the same population has not been resolved by any published study.
Morphology
The colour cue carried in this form's own name is a gold-to-orange ("lion") base coloration, contrasting with the blue, black-barred pattern documented for the nominal C. sp. "Chinyankwazi" population recorded from the same island. Beyond that colour cue, no detailed morphometric description specific to this form has been published in the sources available for this article, and the precise pattern has not been independently confirmed here. It should carry the genus's diagnostic single row of unicuspid, dog-like teeth in each jaw and the compact, moderately elongate body typical of small Cynotilapia. Genus-typical size runs to roughly 3–3.5 in total length, males larger than females.
Habitat
Chinyankwazi Island lies in the southeastern arm of Lake Malawi alongside neighbouring Chinyamwezi Island; both fall within a protected area where ornamental-fish collection is forbidden, per Konings' Cichlids Yearbook coverage of the area's Cynotilapia populations. This is classic mbuna habitat — rocky shoreline and submerged boulder fields interspersed with sand — at the shallow-to-moderate depths where Cynotilapia typically forages, generally within the top 49–66 ft. Water chemistry follows Lake Malawi's standard rocky littoral profile: warm, alkaline, and well-buffered.
Feeding
Cynotilapia's diagnostic unicuspid "dog-tooth" dentition sets its feeding apart from most other mbuna, which use closely packed bicuspid or tricuspid teeth to scrape tightly bound algal turf directly off rock. Cynotilapia species instead pick loose diatoms, filamentous algae, and fine organic detritus from rock and sand surfaces, often foraging over open, sediment-dusted rock rather than defending a dense algal mat. "Lion Chinyankwazi" is presumed to follow this genus-wide feeding pattern, with no dedicated dietary study published for this specific population.
Mating
No breeding behaviour has been documented specifically for "Lion Chinyankwazi". The genus follows the standard mbuna pattern seen throughout Lake Malawi's rocky shore: mature males establish and defend a small territory, often no more than a patch of rock or a shaded crevice, and display to passing females in breeding colour rather than building a nest. Cynotilapia territories tend to be smaller and less fiercely contested than those of larger mbuna genera such as Maylandia or Petrotilapia. Courtship follows the typical haplochromine sequence, with a receptive female circling a displaying male and spawning with him over open substrate.
Breeding
As in every Lake Malawi haplochromine, reproduction is by maternal mouthbrooding. The female takes fertilised eggs into her mouth immediately after spawning and carries them, without feeding normally, until the fry are large enough to be released as free-swimming young; the male provides no further care. Clutch sizes in small Cynotilapia species are modest, typically a few dozen eggs, and the brooding period runs roughly three to four weeks in the genus generally. None of these specifics have been confirmed for the Chinyankwazi Island population itself, so the figures given here are genus-typical expectations rather than documented measurements.
In the aquarium
"Lion Chinyankwazi" is scarce in the trade, since it comes from a protected islet where collection for the aquarium trade is forbidden; any hobby stock traces to earlier collection, before restrictions applied, or to captive breeding lines. Where legitimately kept, standard small-mbuna husbandry applies: abundant rockwork built into caves and broken sightlines, a sand substrate, and water matching Lake Malawi's rocky zone — alkaline, well-buffered (pH roughly 7.7–8.6), and warm (75–82 °F). A tank of at least 39.5–47 in footprint suits a group kept as one male with several females. Diet should lean vegetable, a spirulina-based flake or pellet supplemented sparingly with small invertebrates, with fatty, protein-heavy foods avoided given the genus's general susceptibility to Malawi bloat.
Conservation
"Lion Chinyankwazi" has not been evaluated by the IUCN and, as an undescribed form with no formal scientific name, carries no Red List status of any category. Its documented locality, Chinyankwazi Island, lies within a protected area where ornamental-fish collection is explicitly forbidden, per Konings' field notes — a legal protection that removes the specific pressure of aquarium-trade collecting, though it does not address broader lake-wide threats such as fishing pressure or habitat change. Given the narrow, two-islet range documented for Cynotilapia forms in this area generally, any population here remains inherently exposed to localised risk regardless of trade status.
