概述
橙色尖嘴丽鱼（Julidochromis ornatus）是较常见的洞穴繁殖慈鲷，市售多为人工鱼，也有白化型。它体小但领地性明显，应围绕稳定配对与岩洞空间安排。
分布与栖息地
坦噶尼喀湖特有，主要见于北部岩石过渡带，南端姆普隆古附近也有一种地域型。
饲养环境
一对约需 75 × 30 × 30 厘米，专门繁殖可用约 90 厘米长或更大。沙底配大量岩洞和藏身缝隙，维持稳定环境。不要频繁用大换水剧烈改变条件，配对关系可能因此被破坏。
食性与喂食
主要提供多样活饵和冷冻食物，干粮可较少搭配，并加入含藻饲料或烫菠菜等植物成分。
习性与混养
宜成对，普通小缸不适合多尾同种。可谨慎搭配占用不同区域的合适同湖鱼，让岩洞领地有明确分隔。不同尖嘴丽鱼种和地域型不要混养繁殖。
雌雄区分
成年雌鱼较大；雄鱼生殖乳突更突出、更尖。
繁殖
从幼鱼群自然形成配对可能需一年以上，配对后移出其他鱼；硬凑成年雌雄有严重争斗风险。卵隐蔽产在洞顶或壁面，可达约 100 粒但通常更少，雌鱼照卵、雄鱼守外围。约 2～3 天孵化，鱼苗卵黄吸收后可喂丰年虾无节幼体。亲鱼可多窝连续繁殖，较大幼鱼有时帮忙护卵，但长至约 2.5 厘米应移开。
补充说明
地域型与人工白化型的体色不同，市售繁殖鱼也可能不及野生鱼鲜艳；颜色深浅不是健康或物种身份的唯一判断。

Overview
Common in the hobby, Julidochromis ornatus includes captive-bred and albino forms. Small size does not remove its territorial requirements. A stable pair and a well-divided cave layout are the basis of its aquarium care.
Distribution & habitat
It mainly occurs in rocky transition zones of northern Lake Tanganyika, with an additional form around Mpulungu in the south.
Aquarium setup
A pair can be kept from roughly 75 by 30 by 30 cm, with around 90 cm or more of length suggested for breeding. Use sand and extensive cave-forming rockwork. Maintain stability and avoid abrupt large water changes that may upset the pair.
Diet & feeding
Live and frozen meals should be prominent, with dry food and vegetable matter included for variety.
Behaviour & compatibility
Keep a pair rather than several competing conspecifics in a small tank. Compatible fishes using different areas may be considered. Do not combine julie species or local forms, as they can hybridize.
Sexual dimorphism
Females are larger at maturity; male genital papillae are more pointed and extended.
Breeding
Let juveniles pair naturally and remove surplus fish after bonding. This may take more than a year, while forced adult pairings can be dangerous. Eggs are attached inside a cave and tended by the female as the male guards outside. Hatching usually takes two to three days. Start small live foods after yolk absorption. Successive broods may coexist temporarily and older offspring may assist, but remove them at around 2.5 cm.
Notes
Local and ornamental forms differ in appearance, and captive stock may be less vivid than wild fish. Color intensity alone is not a complete identification clue.
