概述
矶隐带丽鱼（Apistogramma eunotus）是一种体型较小、需要充分遮蔽的短鲷。人工繁殖鱼通常更适合一般混养，野生鱼宜采用更保守的同伴安排；配对中的雄鱼骚扰和雌鱼护幼攻击都需要留意。
分布与栖息地
分布于秘鲁乌卡亚利河及其支流，并沿哥伦比亚、巴西的索利蒙斯／亚马孙水系向东延伸至 Japurá 河流域。记录涉及 Itaya、Samiria、Ampiyacu 和 Yavarí 等水系。栖息环境以缓流溪流、支流及小河为主。
饲养环境
一对可用至少 45 × 30 厘米底面积，群养需要更大空间。茂密植物、沉木及多个小洞可帮助胆怯个体稳定下来，其中一些洞口应小到雄鱼无法进入，供雌鱼退避。软沙、根枝、花盆或合适管道都能提供有效结构。
照明中低，浮水植物有助遮光，避免强流。底部干落叶可释放有机物并培养仔鱼可利用的微生物，但分解也会增加污染负担，应观察水质。低密度条件下可参考每周换水约 10%～15%，避免突然的大幅水质变化。
食性与喂食
以动物性食物为主，野外似乎主要摄取底部无脊椎动物。定期提供丰年虾、水蚤、摇蚊幼虫等活饵或冻饵；多数个体能逐渐接受干粮，通常颗粒较薄片更易被接受。
习性与混养
人工繁殖个体是一般社区缸的优先选择。野生鱼更适合专缸，或搭配小型、安静的陪伴鱼，尽量不混入其他隐带丽鱼属种类。雌鱼应有能避开雄鱼的藏身处，不能把普通装饰洞视为足够的安全安排。
雌雄区分
雄鱼较大、鲜艳，鳍延长较明显。
繁殖
卵通常产在装饰物间的洞穴或裂缝内，由雌鱼照料卵和仔鱼。雌鱼护幼时可能变得非常凶，小缸内必要时应移走雄鱼。
补充说明
本种常以 A73 编号识别，A74～A77 则用于若干外观相似、可能同种的地方种群。它们的关系带有不确定性，保留采集地点比将所有相似编号直接视为同一品系更可靠。

Overview
Apistogramma eunotus is a small dwarf cichlid that benefits from abundant shelter. Captive-bred fish are generally a better community choice than wild specimens. Both male harassment and strong female defense during brood care need consideration when keeping a pair.
Distribution & habitat
The range includes Peru's Ucayali and its tributaries, extending through the Colombian and Brazilian Solimões/Amazon system eastward to the Japurá drainage. Records include the Itaya, Samiria, Ampiyacu and Yavarí. Slow streams, tributaries and small rivers are typical habitats.
Aquarium setup
A pair can use at least 45 × 30 cm of floor space; groups need larger quarters. Dense plants, wood and several small caves help shy fish settle. Some entrances should exclude the male, giving the female a retreat. Sand, roots, pots and suitable pipes all provide useful structure.
Keep light moderate to low and avoid strong current, using floating cover where helpful. Dry leaves release organic compounds and support microbes that supplement fry food, but decomposition also adds a waste burden. Monitor water quality. Weekly changes of approximately 10–15% are a reference for lightly stocked tanks, avoiding sudden major shifts.
Diet & feeding
This primarily carnivorous fish apparently feeds chiefly on bottom-dwelling invertebrates. Offer regular live or frozen brine shrimp, water fleas and bloodworm. Most individuals gradually accept dry foods, often taking pellets more readily than flakes.
Behaviour & compatibility
Choose captive-raised specimens for a general community. Wild fish are better kept in a dedicated aquarium or with small, quiet dither fishes, preferably without other Apistogramma. Provide retreats that genuinely allow the female to escape the male rather than assuming any decorative cave is sufficient.
Sexual dimorphism
Males become larger and more colorful and develop stronger fin extensions.
Breeding
Eggs are normally deposited on a surface within a cavity or crevice. The female tends the clutch and young and may become highly aggressive. Removing the male can be necessary in smaller aquariums.
Notes
A73 is the usual identification code. A74–A77 refer to similar-looking locality populations that may belong to the same species, but their relationship is uncertain. Preserve collection data instead of treating every similar code as an interchangeable breeding line.
