概述
迪氏尖嘴丽鱼（Julidochromis dickfeldi）有深色横纹和带蓝边的鳍，常围绕岩洞活动。它对同种有攻击性，适合按已配对的一对饲养，不能把小型鱼等同于容易合群。
分布与栖息地
坦噶尼喀湖特有，分布在湖西南部卡潘帕至恩多莱之间的浅水岩岸。
饲养环境
已配对一对可从 75 × 30 × 30 厘米考虑，专门繁殖宜再宽敞些。沙底上布置大量稳固岩洞，保持富氧。避免一次大幅换水，因为突然改变环境可能诱发配对双方互相攻击。
食性与喂食
活饵和冷冻食物应占较大比例，干粮可作补充，并定期提供含藻饲料或烫菠菜等植物成分。
习性与混养
有领地性，定区后很少离开。若混养，可选择利用不同空间的合适小中型同湖鱼；多对或多尾同种需要大得多的缸，避免领地重叠。
雌雄区分
外观分性别困难，成年雌鱼一般较大。
繁殖
从幼鱼群自然配对较稳妥，可能等待一年或更久，配对后移走其他鱼；直接购买成年雌雄常不能形成稳定关系。雌鱼在洞壁或洞顶隐蔽产卵，最多约 100 粒但常少得多，雌鱼照卵、雄鱼守外围，约 2～3 天孵化。幼鱼若尚带卵黄，吸收后再喂丰年虾无节幼体。后代可留亲鱼身边较久，也可能协助照看新窝，但长至约 2.5 厘米宜移出，以免被驱逐攻击。
补充说明
属级归属曾受讨论，但这些外观和习性差异不足以在饲养记录中擅自更换学名。

Overview
Dark horizontal bands and blue-edged fins characterize Julidochromis dickfeldi. Its aquarium life centers on rocky shelter. Conspecific aggression makes an established pair preferable to an arbitrary group.
Distribution & habitat
It is endemic to shallow rocky shores in the southwestern part of Lake Tanganyika, between Kapampa and Ndole.
Aquarium setup
A bonded pair can be housed from 75 by 30 by 30 cm, with extra room useful for breeding. Build plentiful stable caves over sand and maintain good oxygenation. Avoid abrupt large water changes, which can disrupt an established pair.
Diet & feeding
Live and frozen foods should make up much of the menu. Include some prepared food and a vegetable component such as algae-containing feed or softened greens.
Behaviour & compatibility
Territories are strongly maintained. Appropriate Tanganyikan fishes using different parts of the aquarium can be considered, but several conspecifics require substantially more space and separated areas.
Sexual dimorphism
Sexing is difficult, though adult females tend to be larger.
Breeding
Natural pairing from juveniles may take a year or longer. Remove surplus fish once bonding occurs; forced adult pairing can end badly. Spawning is concealed on cave walls or ceilings, usually with far fewer than the maximum of about one hundred eggs. The female tends eggs and the male guards outside. Hatching takes two to three days. Feed small live fry food after yolk absorption. Older offspring may assist with later broods, but remove them around 2.5 cm before adults become hostile.
Notes
Its generic placement has been discussed, but the existing species identity should remain attached to stock records.
