Taxonomy & naming
Cynotilapia sp. "Deep Skov" has never been formally described and has no describing authority, no publication date, and no valid-name entry in Eschmeyer's Catalog of Fishes. The name is an informal trade/field designation combining the depth qualifier "Deep" with what is presumably a personal name, "Skov" — a pattern seen elsewhere among Lake Malawi mbuna trade names, which are frequently coined by the collectors, exporters, or aquarists who first brought a form into the hobby rather than by taxonomists. No source consulted for this article confirms the specific person or event behind the name, and none is invented here. The genus Cynotilapia (Regan, 1922) is defined by unicuspid, dog-like teeth, distinguishing it from the bicuspid- or tricuspid-toothed mbuna genera that dominate Lake Malawi's rocky shore.
Morphology
No published morphometric or colour description exists specifically for "Deep Skov". It should carry the genus's diagnostic single row of unicuspid teeth in each jaw and the compact, moderately elongate body typical of small Cynotilapia. Because Three Peaks Reef also hosts a second documented Cynotilapia colour form, sp. "Zebra Deep", the two are presumably distinguishable in the field by colour pattern, but the specific pattern that sets "Deep Skov" apart has not been documented in the sources available here. Genus-typical size for small Cynotilapia runs to roughly 3–3.5 in total length, males larger than females.
Habitat
Three Peaks Reef lies in the southern portion of Lake Malawi and supports at least two named Cynotilapia colour forms at depth — sp. "Deep Skov" and sp. "Zebra Deep" — a pattern consistent with the lake's characteristic fine-grained mbuna speciation, in which a single reef can host multiple closely related but visually distinct populations partitioned by microhabitat or depth. The "Deep" qualifier places this form below the shallow snorkel-depth zone most rock-dwelling mbuna occupy, likely in the range of roughly 49–115 ft based on comparable deep-water mbuna records elsewhere in the lake, though no formal depth survey has been published for this specific population. 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 the bicuspid- or tricuspid-toothed mbuna that scrape tightly bound algal turf off rock. Instead, Cynotilapia species pick loose diatoms, filamentous algae, and fine detritus from rock and sand surfaces. "Deep Skov" is presumed to follow this genus-wide pattern; at the depth this population occupies, light-limited algal growth is likely thinner than in the shallow reef zone, which may push it toward a somewhat greater reliance on picked detritus and small invertebrates, though this has not been directly studied for this form.
Mating
No breeding behaviour has been documented specifically for "Deep Skov". 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 or bower. 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: a receptive female circles a displaying male's territory and spawns 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 Three Peaks Reef population itself, so the figures given here are genus-typical expectations rather than documented measurements.
In the aquarium
"Deep Skov" reaches the hobby only occasionally, given both the narrow reef it comes from and the greater difficulty of collecting fish from depth compared with shallow reef mbuna. Where it is kept, standard small-mbuna husbandry applies: abundant rockwork arranged 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, since male aggression, while milder in this genus than in many mbuna, is still present. Diet should lean vegetable, with a spirulina-based flake or pellet supplemented sparingly by small invertebrates, and fatty, protein-heavy foods avoided given the genus's general susceptibility to Malawi bloat.
Conservation
"Deep Skov" has not been evaluated by the IUCN and, as an undescribed form with no formal scientific name, carries no Red List status — an absence of assessment, not a statement of safety. The documented range is limited to a single reef in the southern lake, and depth alone does not shield a population from over-collection pressure specific to the aquarium trade, since deep mbuna forms attract targeted collecting precisely because of their rarity. No specific population threat has been documented for this form, but its narrow known range is grounds for caution in how heavily the reef is collected.
