概述
斑带尖嘴丽鱼（Julidochromis marlieri）会紧贴岩面游动，不论岩面是斜的还是倒悬。成年同种间很强势，多数缸只适合稳定一对；地域型和近缘种也应分开，以免杂交。
分布与栖息地
坦噶尼喀湖特有，生活于较深的岩岸。湖的南、北端分布较广，东西岸则较零散。
饲养环境
一对至少约 120 × 30 × 30 厘米，成年群体需要明显更大空间。沙底、富氧水与大量稳固岩洞是基础；如果另有岩栖伙伴，各自独立岩堆有助分散争斗。避免很大幅度换水，稳定配对也可能因此失和。
食性与喂食
优质干粮搭配相当比例的活饵、冷冻饵料，也喂含藻饲料或烫菠菜等植物食物。
习性与混养
领地性明确，可谨慎配体型接近、需求相符的同湖鱼，但成年同种不宜在普通缸中多尾拥挤。选择伙伴时不混其他尖嘴丽鱼种或色型。
雌雄区分
成年雌鱼较大；雄鱼生殖乳突更长、更尖。
繁殖
幼鱼自然配对可能需一年或更久，形成稳定关系后分开剩余个体。洞壁或洞顶隐蔽产卵，最多约 100 粒，常更少；雌鱼照卵、雄鱼守洞外。鱼苗卵黄吸收后可吃丰年虾无节幼体，亲鱼通常长期照顾，雌鱼护苗期可成为优势个体。较大幼鱼有时帮助照顾后续窝，但约 2.5 厘米时宜移走以免亲鱼转而攻击。

Overview
Rock-hugging swimming at unusual angles is characteristic of Julidochromis marlieri. Adult conspecifics can be highly confrontational, so most aquaria should house a bonded pair. Keep different locality forms and related species separate to avoid hybridization.
Distribution & habitat
Endemic to Lake Tanganyika, it inhabits relatively deep rocky shorelines. Distribution is broad at the northern and southern ends and patchier along the other shores.
Aquarium setup
A pair needs about 120 by 30 by 30 cm or more. Provide sand, oxygenated water and extensive cave-forming rockwork. Separate rock groups help divide space among compatible rock dwellers. Keep changes gradual because major water replacements can destabilize a pair.
Diet & feeding
Combine a quality prepared feed with live or frozen foods and a vegetable component.
Behaviour & compatibility
Suitable similarly sized Tanganyikan companions may work, but adult conspecific groups require unusually large quarters. Avoid mixing julie species or geographical forms.
Sexual dimorphism
Adult females are larger, while male genital papillae are more elongated and pointed.
Breeding
Pair formation from juveniles can be slow; do not shortcut it by assuming any two adults will bond. Spawning is hidden in a cave, on a wall or ceiling. Females tend eggs while males guard outside. After yolk absorption, fry accept brine-shrimp nauplii. Care can be prolonged, with the female becoming dominant while tending young. Older fry may help with new broods, but should be removed around 2.5 cm as tolerance can end.
