Taxonomy & naming
Maylandia sp. "Aurora Bevous" has no describing author, no year of publication, and no FishBase entry. Its trade name pairs "Aurora" — a reference to its resemblance to the formally described Maylandia aurora (Burgess, 1976) — with "Bevous", a qualifier of uncertain origin not explained in the sources consulted for this article; no invented meaning is offered for it here. Because Maylandia aurora itself is already documented from Chizumulu Island under its own name, this undescribed form should not be assumed identical to that population; it is treated as a separate, unnamed form pending formal study, resembling M. aurora in general appearance but not established as conspecific with it. Maylandia (also placed by some authors in the competing genus Metriaclima) is the large "zebra mbuna" radiation of Lake Malawi, within which many locality- and colour-based populations remain undescribed.
Morphology
Maylandia aurora, the species this form is named for, is a moderately sized mbuna in which breeding males show a blue-violet body crossed by a dark horizontal stripe, with a bright orange-red flush washing over the back and into the dorsal fin — the colour pattern behind the species' name, aurora, Latin for "dawn". Females are typically plainer, pale with faint barring. Whether "Aurora Bevous" reproduces this exact pattern has not been confirmed by any published account; it is presented here as resembling M. aurora in the trade, without asserting that its males show an identical orange-and-blue arrangement. No measurements specific to this form have been published; genus-typical Maylandia size is assumed pending direct documentation.
Habitat
This form is recorded from Chizumulu Island and nearby Mkanila Bay, both in the open, offshore northeastern part of Lake Malawi on the Malawian side. Chizumulu is a small, isolated rocky island well out in the lake, hosting a cichlid community with a number of locality-restricted endemics and colour forms, including the formally described Maylandia hajomaylandi and locality forms of M. aurora itself. Maylandia as a genus is a rock-dwelling mbuna group, occupying the surge zone and boulder fields close to shore. Water conditions follow Lake Malawi's typical rocky-habitat envelope: warm, alkaline, and well-buffered, at moderate depths on the rock face.
Feeding
Maylandia is, genus-wide, an aufwuchs grazer: the fish rasp algae, diatoms, and associated micro-organisms from the surface of submerged rock using specialised bicuspid teeth, supplementing this with zooplankton picked from the water column over the reef. No feeding study specific to "Aurora Bevous" has been published, but this dietary pattern is close to universal across the genus and is a reasonable expectation for this form as well.
Mating
Male mbuna of the Maylandia zebra complex are territorial rock-holders, defending a patch of reef against rivals and displaying to passing females with no lasting pair bond — the standard lek-like social structure of the genus. No courtship account specific to this form has been published, so its behaviour is presented here as genus-typical rather than independently documented.
Breeding
As with every Lake Malawi cichlid, Maylandia sp. "Aurora Bevous" is presumed to be a maternal mouthbrooder: the female lays eggs, takes them into her mouth, and is drawn to the egg-spot markings on the male's anal fin, whose pursuit causes her to take in milt that fertilises the clutch already in her buccal cavity. She then broods the eggs and fry for roughly three weeks before releasing free-swimming young, with no male or post-release parental care. No clutch size has been documented for this specific form; genus-typical Maylandia broods run from roughly a dozen to several dozen eggs depending on female size.
In the aquarium
Maylandia sp. "Aurora Bevous" is a specialist form rather than a mainstream trade fish, and hobbyist experience with it specifically is limited. Keepers should follow standard Maylandia husbandry: a large rockwork structure with plenty of caves and broken sightlines, fine sand substrate, and alkaline, well-buffered water in the range of roughly 75–82 °F and pH 7.7–8.6. Diet should lean heavily plant-based — spirulina flake, algae wafers, and blanched vegetables — with meaty foods limited to occasional supplements, since chronic high-protein feeding predisposes mbuna to the bloat syndrome common in the genus. A single male with several females is the standard, lowest-stress social arrangement; males should not be paired with visually similar Maylandia, which draws disproportionate territorial aggression.
Conservation
Maylandia sp. "Aurora Bevous" has no IUCN Red List assessment, since formal evaluation requires a validly published scientific name and none exists for this form. Its resembled relative, Maylandia aurora, is a wide-ranging species assessed at genus-typical conservation concern levels, but that status cannot be extended to this separate, unnamed population. As a rock-restricted endemic of the Chizumulu Island area, it shares the general pressures documented across Lake Malawi's island-endemic mbuna — a naturally narrow range, localised habitat sensitivity, and exposure to the ornamental collecting trade — but no population-specific data exist to characterise its status beyond that general context.
