概述
六带新亮丽鲷（Neolamprologus sexfasciatus）是攻击性强的捕食鱼，不适合普通坦湖混养缸。它的鱼对关系并非始终稳定，产卵和育幼结束后雄鱼也可能攻击雌鱼，躲藏处不能只为配对前准备。
分布与栖息地
坦噶尼喀湖特有，仅见于湖南部坦布韦角至卡雷马之间，主要利用较浅岩区及砂底上散布岩石的过渡地带。
饲养环境
用岩堆形成洞穴，中间保留开放游动区，铺砂底。肉食性大鱼会产生较多排泄负担，过滤应有效。雌鱼随时能避开的藏身处十分重要，稳定配对后也应保留。
食性与喂食
自然为食鱼性，投喂多样的动物性活饵或冷冻饵料，辅以优质慈鲷颗粒。混养时应把体型较小的鱼视作潜在食物。
习性与混养
领域性强且对同种十分凶，除极大空间外以单对为限。大型缸可谨慎尝试体型匹配、活动区域不同的坦湖伙伴，其他岩栖鱼必须有独立领域。即使同体型鱼也未必能长期和平共处。
雌雄区分
外观难以准确区分，成年雄鱼往往更大。
繁殖
人工繁殖有成功但不常见，双亲洞穴产卵。从幼鱼群自然配对可能需要一年或更久，配对后必须移走其余个体。直接合养陌生成鱼不能保证成对，雌鱼甚至可能被追逐致死。
鱼对常自己挖整洞穴，雌鱼在洞底产卵，主要照卵，雄鱼强烈守卫外围。由于产卵隐蔽，发现疑似育幼时可提前准备适口鱼苗饵料。自由游动的幼鱼能吃丰年虾无节幼体。之后雌鱼继续照顾约两三周，再由雄鱼接手，此时雄鱼可能再次排斥雌鱼。
补充说明
不同产地型的底色可呈蓝、黄或白，但颜色变化不减轻其攻击与捕食特性。配对与育幼期间都要持续观察鱼对关系。

Overview
The predatory Neolamprologus sexfasciatus is too aggressive for a general Tanganyikan community. Pair bonds can weaken between breeding events, and a male may attack his partner after spawning or during changes in brood care. Retreats remain necessary even after pairing.
Distribution & habitat
It is endemic to southern Lake Tanganyika between Cape Tembwe and Karema. Relatively shallow rocky areas and transitions of scattered stones over sand are typical.
Aquarium setup
Arrange rock piles into caves with open swimming areas between them over sand. Efficient filtration must cope with the waste from a meaty diet. Maintain shelters the female can use throughout the pair's life together.
Diet & feeding
It naturally eats fish. Offer varied meaty live and frozen foods with quality cichlid pellets as a supplement. Small prospective companions should be regarded as prey.
Behaviour & compatibility
Strong territorial and conspecific aggression limits most aquaria to one pair. Very large setups may allow carefully chosen, appropriately sized Tanganyikan fishes using different areas. Other rock dwellers need independent territories. Similar size alone does not guarantee compatibility.
Sexual dimorphism
External sexing is difficult, although adult males tend to grow larger.
Breeding
Aquarium successes are infrequent. Raise juveniles for natural pairing, which may take a year or longer, and remove extras once a pair forms. Forcing unrelated adults together can lead to fatal harassment of the female.
The pair often excavates a cave and lays eggs on its floor. The female tends them while the male strongly guards outside. Spawning is easily missed, so have suitable starter food ready when brood care is suspected. Free-swimming fry take Artemia nauplii. The female cares for them for another two or three weeks, after which the male assumes the role and may reject her again.
Notes
Locality forms vary in ground color from blue to yellow or white. This variation does not reduce the species' predatory and aggressive nature. Pair relationships require observation throughout reproduction.
