概述
亮丽鲷（Lamprologus signatus）是雌雄外观差别很大的贝居慈鲷：雄鱼有明显体侧横带，雌鱼则没有。买鱼时应先确认性别及身份，不能因花纹不同就把两性当成不同种。
分布与栖息地
本种为坦噶尼喀湖特有鱼，具名记录包括 Kabwe Ngosye 和 Nundo 岬一带。它生活在湖岸较深、底质柔软且空螺壳聚集的区域。
饲养环境
一对或三条组合可参考约 45 × 30 × 30 厘米的缸，群落需更大空间。安排大片开阔沙底，沙层至少约 5 厘米，并提供多于鱼数的空壳。若准备繁殖，每条雌鱼约需 4～5 个壳供选择及搬移幼鱼使用。水应硬而偏碱。
食性与喂食
主要提供活饵及冻饵，通常也能接受干粮。用适口且多样的食物维持亲鱼体况，避免长期只依赖单一饵料。
习性与混养
本种会积极守卫贝壳及周围小片领地。可以考虑使用其他水层或岩区的适当坦湖鱼作同伴，但不应让它们持续占据壳区。雄鱼对同种雄鱼很凶，除非缸足够大，否则只保留一条雄鱼。
雌雄区分
雄鱼较大，体侧具有清晰垂直横带，雌鱼缺少这些条纹。雌雄曾因差别太大而分别被描述为不同种，挑选配对时尤其应留意。
繁殖
在螺壳内产卵，若想提高整窝成活率宜用专缸。繁殖可参考 pH 8.0～8.5、25～26.5 °C，一雄配多雌较容易开展。配对关系只是较松散地持续到幼鱼能独立，后续双方都可能更换伴侣。
雌鱼在壳口展示，入壳产卵后出来，由雄鱼进入受精。与部分仅雌鱼护幼的贝居鱼不同，本种双亲都参与照顾，并会把整窝幼鱼在不同壳间搬迁。仔鱼自由游动时可吃丰年虾无节幼体或微虫；单独育幼可能提高成活率，尽管亲鱼通常不伤幼鱼。

Overview
Lamprologus signatus is a shell-dwelling cichlid with striking differences between the sexes. Males have clear vertical flank bars while females lack them. Check identity and sex when purchasing rather than assuming that differently patterned fish belong to different species.
Distribution & habitat
It is endemic to Lake Tanganyika, with named localities around the Kabwe Ngosye and Nundo capes. The species occupies relatively deep shoreline water over soft bottom where empty snail shells accumulate.
Aquarium setup
A tank around 45 × 30 × 30 cm is a reference for a pair or trio; colonies need more space. Provide broad sandy areas at least approximately 5 cm deep and more shells than fish. For breeding, allow roughly four or five shells per female, accommodating selection and later brood transfers. Water should be hard and alkaline.
Diet & feeding
Live and frozen foods should predominate, although dry foods are generally accepted. Use varied, suitably sized foods to maintain condition rather than depending permanently on one item.
Behaviour & compatibility
Shells and the small surrounding territories are defended vigorously. Appropriate Tanganyikan fishes using other water layers or rocky areas may be considered, provided they do not continually intrude into the shell zone. Males are strongly aggressive toward one another, so keep only one unless the aquarium is large.
Sexual dimorphism
Males grow larger and display distinct vertical bars absent in females. The sexes once looked different enough to be described separately, making careful selection especially useful when assembling breeding fish.
Breeding
Eggs are laid inside shells. A dedicated aquarium offers better prospects for raising a full brood. Around pH 8.0–8.5 and 25–26.5 °C are breeding references, and one male with several females is a practical arrangement. Bonds are loose, lasting through early brood development rather than implying permanent monogamy.
The female displays at an entrance, enters to lay and then leaves so the male can fertilize the clutch inside. Unlike shell dwellers in which only the female cares for young, both parents participate and regularly move the entire brood between shells. Free-swimming fry take brine-shrimp nauplii or microworms. Separate rearing may improve survival, even though the parents usually do not harm them.
