概述
Nannacara taenia 是来自巴西的小型条纹慈鲷，性情较胆怯，适合安静、有植物遮蔽的环境。繁殖时雌鱼在洞内照顾卵，雄鱼守卫外围，日常胆小并不意味着护幼期间没有领域行为。
分布与栖息地
已知仅分布于帕拉州贝伦附近的托坎廷斯河流域一带，生活在水草密集的小溪中。
饲养环境
至少约 60 × 38 cm 的底面积，水草种植要较密，同时可用沉木与枝条增加遮蔽。砂底较合适，保持中等水流，灯光不要过强。适宜范围中段的温度较合适，水以软水为佳。
食性与喂食
缸内通常不挑食，可接受多种干粮及调配饲料。应定期轮换红虫、丰年虾等活饵或冻饵，不能只因为能吃干粮就省去多样化投喂。
习性与混养
伙伴应限于温和的群养鱼，例如合适的小型灯鱼、小型鲤科鱼或鼠鱼。强势、喧闹的同缸鱼会让它难以放松。准备繁殖时，独立繁殖缸比混养环境更容易提供安稳条件。
雌雄区分
本条记录中雄鱼较小。雌鱼另有一条与主要体侧纹平行的线，雄鱼没有；雌鱼进入繁殖状态后颜色明显变深。
繁殖
可用活饵调理亲鱼，红虫尤其受欢迎。配对后在小洞或带小入口的倒置花盆内产卵，卵附着于洞壁，由雄鱼受精。随后雌鱼守在洞内照料卵，雄鱼护卫较大的外围领域。
孵化约需 2–4 天，随温度变化；再过约四天幼鱼自由游动。开口可用新孵化的丰年虾及细粉仔鱼粮。让亲鱼有足够安全感往往比强行催产更关键。
补充说明
日常体色可偏朴素的棕褐色，不能仅凭鲜艳程度判断健康或身份。繁殖状态下的深色与平行条纹，应结合个体状态一起观察。

Overview
Nannacara taenia is a small striped Brazilian cichlid that favors a quiet, sheltered setting. Its shy everyday behavior does not eliminate breeding territoriality: the female tends eggs inside a cave while the male guards the surrounding area.
Distribution & habitat
It is known from a restricted part of the Tocantins basin near Belém in Pará, Brazil, where it inhabits small streams with dense vegetation.
Aquarium setup
Allow a footprint of at least about 60 × 38 cm. Dense planting, wood, and branches provide cover. Sand is preferable, flow should be moderate, and lighting should not be intense. Temperatures near the middle of the established range are suitable, with soft water favored.
Diet & feeding
Aquarium fish generally accept a range of dry and prepared foods. Regularly include live or frozen bloodworms and brine shrimp rather than treating acceptance of dry food as a reason to omit dietary variety.
Behaviour & compatibility
Restrict companions to peaceful community fish, such as suitable small tetras, small barbs, or cory-type catfish. Forceful or disruptive tankmates undermine the security this fish needs. A dedicated breeding aquarium offers calmer conditions than a mixed community.
Sexual dimorphism
The male is recorded as the smaller sex. Females have an additional line running parallel to the main flank marking, absent in males. Reproductive females become substantially darker.
Breeding
Condition fish with live foods, particularly bloodworms. Spawning occurs in a small cave or inverted pot with a small entrance. Eggs attach to the interior wall and are fertilized by the male. The female then guards them inside while the male defends the wider territory.
Incubation takes about two to four days, depending on temperature. Free swimming follows roughly four days later. Newly hatched brine shrimp and finely powdered fry foods are suitable first foods. Establishing a secure environment is central to successful breeding.
Notes
Ordinary coloration can be subdued brown. Brightness alone is not a reliable measure of identity or condition; interpret the darker breeding dress and parallel markings in context.
