Taxonomy & naming
Labidochromis sp. "Textilis Blue" has no describing author, no year of publication, and no FishBase page. It circulates in the hobby and field literature under the informal name "textilis", used by collectors and Ad Konings's field surveys for a loosely defined cluster of similar-looking, predominantly blue Labidochromis found along the lake's southeastern shore, with "Blue" and the localities Lumessi and Thundu further narrowing this particular population within that cluster. "Textilis" functions here as a trade-name group label rather than a validly published species epithet; no combination of Labidochromis and textilis appears as an accepted name in Eschmeyer's Catalog of Fishes. This form should be treated strictly as an undescribed, locality-based population and not conflated with any other blue Labidochromis carrying a superficially similar name from elsewhere in the lake.
Morphology
Field and trade accounts describe this form as a blue-bodied Labidochromis, consistent with the broader "textilis" group from which it takes its name, though a detailed published colour description specific to this Lumessi/Thundu population has not been located for this article. Labidochromis as a genus carries specialised outer teeth suited to grazing aufwuchs or picking small invertebrates from rock crevices, and body shape across the genus ranges from robust to slender depending on feeding mode; where this form sits on that spectrum has not been formally documented. Rather than invent detail beyond the "Blue" in its trade name, this account limits itself to what is actually known: a blue Labidochromis of genus-typical size and build from the Mozambican shore.
Habitat
Labidochromis sp. "Textilis Blue" is recorded from Lumessi and Thundu, two localities on the Mozambican shore of Lake Malawi. This stretch of coast sits within the lake's less-studied southeastern reaches, where several deeper, less commonly collected Labidochromis populations have been documented alongside the region's better-known mbuna fauna. The "textilis" group as a whole is associated with rocky habitat, often at somewhat greater depth than the shallow-water Labidochromis species most familiar to aquarists. Water conditions follow Lake Malawi's typical hard, alkaline inshore chemistry; no depth figure specific to this exact population has been published, so a genus-typical rocky-reef range is used here rather than a documented number.
Feeding
No dedicated feeding study exists for Labidochromis sp. "Textilis Blue". Rock-dwelling Labidochromis generally either rasp aufwuchs from stone surfaces or pick small invertebrates — insect larvae, micro-crustaceans, zooplankton — from crevices and biofilm, and several species combine both strategies. Absent a specific account for this form, its diet is presented here as genus-typical rock-associated feeding rather than a documented fact.
Mating
Courtship and territoriality have not been documented for this specific form. By the general pattern seen across rock-dwelling Labidochromis, males are expected to hold small territories among boulders or in crevices, display to passing females with no lasting pair bond, and compete with rival males for the best sites. Whether this population follows that pattern precisely, and any details particular to it, have not been recorded in the sources available to this article.
Breeding
Labidochromis sp. "Textilis Blue" is presumed to be a maternal mouthbrooder, as is every Lake Malawi cichlid: a female takes fertilised eggs into her mouth and carries them through incubation to free-swimming fry, with the male playing no further role after spawning. No clutch size, brood duration, or other breeding data specific to this form have been published. Genus-typical Labidochromis broods run to a few dozen eggs, offered here as a general expectation rather than a documented count for this population.
In the aquarium
Labidochromis sp. "Textilis Blue" is a specialist, infrequently traded form rather than a mainstream aquarium fish, and hobbyist experience with it is limited compared with widely kept Labidochromis such as the electric yellow, L. caeruleus. A keeper who obtained it should provide the standard rocky Lake Malawi setup — ample rockwork with caves and crevices, a fine sand substrate, and hard, alkaline water in the range of roughly 75–82 °F and pH 7.7–8.6 — and offer a varied diet combining plant-based flake with small meaty foods, given the genus's mixed feeding habits. No species-specific husbandry record exists for this form, and general Labidochromis and mbuna practice is offered here only as a starting point.
Conservation
Labidochromis sp. "Textilis Blue" has no IUCN Red List assessment, since formal evaluation requires a validly published scientific name and none exists for this form. As a locality-restricted rock-dwelling cichlid from a comparatively under-surveyed stretch of the Mozambican shore, it shares the general pressures documented across Lake Malawi's rock-associated endemics — sedimentation, localised habitat disturbance, and ornamental collecting — but no population-specific data exist to characterise its status beyond that general context.
