概述
蓝腹彩短鲷（Nanochromis parilus）是较常见的彩短鲷属鱼，但软酸水与配对管理仍有要求。平时对合适的其他鱼相对温和，对同种却可能很强势，适合从一对和多处遮蔽开始规划。
分布与栖息地
来自刚果民主共和国，栖息于溪流中水流较慢的地带。
饲养环境
提供充足洞穴和躲藏处，可使用花盆、岩石、树根及沉木，底部铺砂供挖掘。水草可以增加遮蔽，泥炭过滤也能辅助软酸环境。多对同养必须有更大的底面积，各自可避开其他鱼的领域。
食性与喂食
通常接受大多数食物，但应以多样活饵和冷冻饵料为主要部分，不能仅因吃干粮就长期简化食谱。
习性与混养
可考虑适应软酸水的小型温和鱼，其他矮慈鲷则需要特别注意空间。同种配对外的个体可能遭到驱赶，尚未成熟的雌鱼也要能躲开雄鱼的求偶压力。
雌雄区分
雌鱼颜色更浓，腹部有紫色光泽；雄鱼成年后更大，背鳍和臀鳍有短延长。
繁殖
雌雄共同育幼，在岩石或沉木下挖洞产卵，繁殖并不算简单。水应很软而偏酸，避免高于六点五的酸碱值，配合温和海绵过滤。雌鱼以弯身展示紫色腹部，双方扩鳃、发色并整理洞穴；提供多处遮蔽有助于未准备好的雌鱼避让。
雌鱼主要照卵，雄鱼守卫产卵地，偶尔交换任务。约两三天孵化，约第七天自由游动后可吃微虫和丰年虾无节幼体。鱼苗早期对酸碱和硬度变化敏感，保持很软、酸性且稳定的水，待长大再缓慢调整。护幼一般持续约一个月，亲鱼吞食鱼苗较少见。
补充说明
雄鱼尾鳍上半部有条纹，雌鱼尾鳍下部通常没有花纹，可用于区别裸头彩短鲷（Nanochromis nudiceps）。即使贸易中较常见，也不意味着水质要求可以忽略。
English
Overview
Nanochromis parilus is among the more familiar members of its genus, but still requires attention to soft acidic water and pair relationships. It can be relatively tolerant of suitable other fishes while remaining aggressive toward its own kind.
Distribution & habitat
It originates in DR Congo, occupying slower sections of streams.
Aquarium setup
Offer abundant retreats using pots, rocks, roots, and driftwood over sand. Plants add optional cover, and peat filtration can assist the soft acidic setting. More than one pair needs much greater floor space and separate areas.
Diet & feeding
Most foods are accepted, but a varied selection of live and frozen items should dominate. Readiness to eat dry food is not a reason to provide an unvaried diet.
Behaviour & compatibility
Small peaceful companions sharing its water requirements can work. Other dwarf cichlids require careful consideration of space. Extra conspecifics may be driven away, and an unready female needs shelter from persistent male pursuit.
Sexual dimorphism
Females have stronger overall color and a violet abdomen. Adult males become larger and develop short dorsal and anal extensions.
Breeding
Pairs excavate beneath rocks or wood and share care of cave-spawned young. Breeding is demanding, requiring very soft acidic water, generally below pH six and a half, with gentle sponge filtration. Females curve to display the belly, followed by intensified color, gill displays, and cave preparation. Multiple retreats help a female avoid pressure before she is ready.
The female primarily tends eggs while the male guards, with some exchange of duties. Hatching takes two to three days and free swimming begins around day seven. Offer microworms and Artemia nauplii at that stage. Early fry are sensitive to shifts in pH and hardness, so maintain stable soft acidic conditions and only adjust gradually as they grow. Care typically continues for about a month, and parental predation is uncommon.
Notes
Upper-tail bars in males and an unpatterned lower tail in females help distinguish this fish from Nanochromis nudiceps. Greater trade availability does not imply less demanding water requirements.
