概述
Apistogramma alacrina 的胸鳍基部上下有暗色斑块，是辨认时值得留意的特征。它适合遮蔽充分、轻流的小型慈鲷环境，诱产不一定困难，但早期鱼苗对水质变化非常敏感。
分布与栖息地
来自哥伦比亚中部的阿里阿里—瓜维亚雷水系，属奥里诺科流域；也见于邻近奥尔特瓜萨河，经卡克塔河进入亚马孙流域。模式地点是一处路边水池，可能也住在落叶聚集的缓流支流、回水区和小溪。
饲养环境
软砂、沉木枝根形成阴影和洞穴，也可使用花盆洞、管段等人工藏处。加入适量干落叶能形成自然覆盖和微生物，鱼苗可从中获得附加食物；落叶可逐渐分解，或数周更换一次。
照明宜柔和，耐阴水草、莫丝及少量浮水植物有助遮光。过滤水流轻柔，在低密度缸中每周约一至一成半的小量换水可作为维护参考，避免突然大幅改变水质。
食性与喂食
隐带丽鱼属整体以动物性食物为主，野外多摄食底部小型无脊椎动物。本种可规律提供丰年虾、水蚤及红虫等活饵、冷冻饵；尝试干饲料时，小颗粒往往比薄片更容易接受，但要观察实际进食。
习性与混养
更适合单种或配少量小型温和陪游鱼，尽量避免与其他同属鱼混养。成对饲养也要有遮挡和退路，尤其在雌鱼护卵时。
雌雄区分
雄鱼更大、色彩较鲜明，鳍也比雌鱼延长。
繁殖
底质产卵，通常选择造景中的狭缝或洞穴。雌鱼主要照料卵和鱼苗，小缸中她可能强烈驱赶雄鱼，必要时应移走雄鱼。
育苗初期对水质变化特别敏感，应每天多次少量喂食，并进行规律、轻量的部分换水；避免为了追求清洁而一次换掉大量水。
补充说明
若干外观很像的商品鱼使用 A106、A107、A108 编号，它们与本种是否全部同种尚未厘清。维持繁殖群时保留编号、产地和来源信息，不应仅因外观近似便混合。

Overview
Dark markings above and below the pectoral-fin base help identify Apistogramma alacrina. Sheltered, gentle-flow conditions suit this dwarf cichlid. Obtaining eggs can be easier than rearing young through their sensitive early weeks.
Distribution & habitat
Records span Colombia’s Ariari–Guaviare drainage in the Orinoco basin and the Orteguaza–Caquetá system in the Amazon basin. The type site was a roadside pool. Slower tributaries, creeks, and backwaters with accumulated leaves are considered likely habitat.
Aquarium setup
Use soft sand with wood and roots forming shaded cavities, or artificial shelters such as pots and pipe sections. Leaf litter adds cover and microorganisms that can supplement fry feeding; allow it to decompose or replace it periodically.
Subdued lighting suits shade-tolerant plants and moss, with floating vegetation providing further diffusion. Keep filtration gentle. In lightly stocked tanks, weekly changes of around 10–15% are a suggested approach, avoiding abrupt chemical shifts.
Diet & feeding
The genus generally feeds chiefly on small benthic invertebrates. Offer regular live or frozen Artemia, Daphnia, and bloodworms. Small pellets may be accepted more readily than flakes when introducing dry food, but check individual feeding responses.
Behaviour & compatibility
A species setup or carefully selected small dither fishes is preferable to mixing it with other members of the genus. Even paired fish need cover and escape routes, especially when the female guards a brood.
Sexual dimorphism
Males are larger, more colorful, and develop longer fins than females.
Breeding
Eggs are normally placed in a crevice or cavity, with the female taking most responsibility for eggs and fry. In small aquariums she may attack the male strongly enough that removal is needed.
Early fry are sensitive to changes in water chemistry. Successful rearing relies on several small meals per day and regular modest partial changes rather than large exchanges.
Notes
Similar trade fishes carry the codes A106, A107, and A108, but their species limits remain unresolved. Keep locality, code, and provenance records when maintaining breeding lines.
