概述
穆氏新亮丽鲷（Variabilichromis moorii）成鱼体色较暗，而不同产地的幼鱼可能为暗色、黄色或橙色。整体性情相对温和，繁殖时仍会积极护幼，同种配对之间也需要清楚分开的领地。
分布与栖息地
坦噶尼喀湖特有，仅见于湖南部，栖息于岩石岸边的浅水区域。
饲养环境
沙底配大量石洞，在岩石之间留少量开放水域。一对鱼日常饲养可从约 75 × 30 × 30 cm 的缸开始，专门繁殖时建议采用至少约 120 cm 长的缸，给亲鱼与逐渐长大的幼鱼更多空间。
食性与喂食
活饵和冻饵可占较大比例，干粮适量补充，同时提供螺旋藻等植物性食物。本种会摄食丝状藻类。
习性与混养
可与占据不同空间的中小型坦湖慈鲷混养。若选择其他岩栖鱼，需更大空间并保证各自有领地；不要搭配强势、躁动的种类。宜成对饲养，配偶关系持久。除非缸非常大，一缸只保留一对同种。
雌雄区分
外观分辨困难。成年雄鱼腹鳍通常较长，背鳍和臀鳍也略为延伸。
繁殖
让幼鱼自然配对后移出多余同种。产卵很隐蔽，卵散布附着在洞壁或洞顶，往往看到鱼苗才察觉已经繁殖。雌鱼照顾卵，雄鱼守卫外围。
约一周后可见自由游动的鱼苗离洞，但初期仍靠近洞穴，由双亲积极保护。鱼苗能吃丰年虾无节幼体；亲鱼护幼时间较长，幼鱼可留至约 2.5 cm 后再移出，以免成鱼开始攻击它们。在这之前亲鱼可能再次产卵，较大的幼鱼仍留在领地内，甚至参与照顾新一窝。
补充说明
黄色或橙色幼鱼会逐渐转为成鱼暗色。已有观察认为，这些变色类型可能把幼鱼混入其他拥有相近幼鱼体色的种类中，由其代养，从而增加自身繁殖机会；这应视作行为观察而非必然出现的饲养现象。贸易中还可能使用旧称 Neolamprologus moorii。
English
Overview
Adult Variabilichromis moorii are dark, but juveniles can be dark, yellow, or orange depending on locality. Its generally mild disposition does not eliminate defense of young or conflict between conspecific pairs. Long-term pair bonds are central to its social arrangement.
Distribution & habitat
This Tanganyikan endemic is restricted to the southern lake, where it occupies shallow rocky shoreline habitats.
Aquarium setup
Provide a sand bed with extensive cave-forming rockwork and small open spaces between structures. Around 75 × 30 × 30 cm can accommodate a pair for routine maintenance; a dedicated breeding aquarium is recommended at a length of approximately 120 cm or more, allowing additional family space.
Diet & feeding
Live and frozen foods can supply much of the diet, with dry foods used less frequently. Include plant material such as spirulina preparations. The species also eats filamentous algae.
Behaviour & compatibility
Small or medium Tanganyikan cichlids using other areas of the aquarium are possible companions. Other rock dwellers require ample room and separate territories. Avoid boisterous, forceful species. Keep an established pair, with only one conspecific pair unless the aquarium is very large.
Sexual dimorphism
External sexing is difficult. Adult males generally have longer pelvic fins and slightly more extended dorsal and anal fins.
Breeding
Allow youngsters to pair naturally and remove surplus conspecifics. Eggs are attached separately across a cave wall or ceiling, with spawning sufficiently hidden that the brood may go unnoticed until fry emerge. The female attends the eggs while the male guards the surrounding area.
Free-swimming fry can appear outside the cave after about a week, remaining nearby under active parental defense. They accept Artemia nauplii. Care continues for an extended period, but move offspring once they approach 2.5 cm because the adults may turn against them. Before that stage, another spawning may occur, with older offspring remaining in the territory and even helping attend the new brood.
Notes
Yellow or orange juveniles darken as they mature. Observations suggest that forms showing this change may place young among similarly colored offspring of other species, gaining foster care and allowing more frequent spawning. This is a reported possibility rather than an inevitable aquarium behavior. The trade name Neolamprologus moorii may also be encountered.
