概述
裸头彩短鲷（Nanochromis nudiceps）需要很软的酸性水，对育苗期水质波动尤其敏感。它对合适的异种伙伴相对温和，但同种之间可能有明显冲突，稳定鱼对与充足藏身处比单纯增加数量更合适。
分布与栖息地
分布于刚果民主共和国的中部盆地区域。
饲养环境
用花盆洞穴、岩石、根和沉木提供多个躲藏处，砂底方便挖掘。水草不是必需，但额外遮蔽有帮助；可利用泥炭过滤辅助形成软酸环境。单对需要独立空间，多对则需更大的缸及各自领域。
食性与喂食
一般接受多种食物，但活饵和冷冻饵料应占较大比例，食物保持多样以帮助亲鱼成熟。
习性与混养
可搭配能适应同样软酸水的小型温和鱼。其他矮慈鲷只能谨慎考虑，不能因异种相对和平而忽略空间。对同种较强势，尤其雄鱼求偶时可能追逼尚未准备好的雌鱼。
雌雄区分
雌鱼整体色彩更浓，腹部有紫色光泽；成年雄鱼背鳍和臀鳍通常有短延长。
繁殖
双亲照顾的洞穴产卵鱼，水质要求严格，繁殖需要酸性条件，酸碱值高于六点五时不易成功。以温和气动海绵过滤维持很软的水，用木石下的洞及多处躲藏空间减少雌鱼压力。雌鱼主动求偶，弯成类似字母 S 的姿势展示紫腹，双方发色并扩鳃，随后挖掘产卵洞。
雌鱼主要照卵，雄鱼守外围，分工有时会交换。卵约两三天孵化，约第七天自由游动，即可吃微虫及丰年虾无节幼体。早期鱼苗必须保持很软、酸性且稳定的水，酸碱或硬度突变可造成大量损失；长大后再缓慢适应更普通的条件。亲鱼护幼约一个月，之后可能再繁殖。
补充说明
容易与蓝腹彩短鲷（Nanochromis parilus）混淆：本种雄鱼尾鳍上半部没有条纹，体鳞有暗边，雌鱼尾鳍下部带点斑。其严格水质需求使它不适合作为随意尝试的入门鱼。
English
Overview
Nanochromis nudiceps requires very soft acidic water, with early fry particularly sensitive to changes. Compatible other species may be tolerated, but conspecific disputes favor keeping an established pair with ample retreats rather than an arbitrary group.
Distribution & habitat
It occurs in the Cuvette Centrale region of DR Congo.
Aquarium setup
Provide several shelters using pots, rocks, roots, and wood. Sand accommodates digging. Plants are optional but add cover, and peat filtration can assist the soft acidic arrangement. Multiple pairs require a much larger aquarium with separate areas.
Diet & feeding
Most foods are accepted, but live and frozen items should form the greater part of a varied diet, particularly when conditioning breeders.
Behaviour & compatibility
Small peaceful fishes comfortable in the same soft acidic water are possible companions. Other dwarf cichlids require caution and adequate space. Relative tolerance of different species does not remove conspecific aggression, especially when a male pursues a female that is not ready to breed.
Sexual dimorphism
Females are more intensely colored, including a violet abdomen. Adult males usually develop short dorsal and anal extensions.
Breeding
Both parents care for cave-spawned young. Very soft acidic water is needed, with spawning inhibited above approximately pH six and a half. Gentle sponge filtration and several retreats beneath wood or stone help accommodate the pair. Females initiate courtship, curving to display the violet belly. Intensified color and gill displays precede excavation of a spawning cave.
The female usually tends eggs while the male guards outside, though roles can partly exchange. Eggs hatch in two to three days and fry swim freely around day seven. Microworms and Artemia nauplii are suitable immediately. Early development requires stable, very soft acidic water; abrupt pH or hardness changes can cause severe losses. Brood care lasts about a month, and growing juveniles can gradually be acclimated to less specialized conditions.
Notes
This species resembles Nanochromis parilus. Males lack upper-tail bars and have dark scale edges, while females show spots low in the tail fin. Its demanding water requirements make it unsuitable for a casual first attempt at dwarf cichlids.
