概述
黑带泥鮰（Limia nigrofasciata）的成年雄鱼会出现明显隆背，这是脊背处脂肪组织积累形成的特征。它是容易繁殖的卵胎生鱼，适合植物较丰富、又留有游泳空间的环境，需避免软酸水。
分布与栖息地
原产海地和多米尼加共和国，常成大群活动于水草密集的浅水区，若干地点也有半咸水种群。
饲养环境
可从长约 45 cm、容积约 41 L 的缸起步，密植区与开放水域相结合。总体对布置不苛刻，但雌鱼需要躲避雄鱼的草丛。
食性与喂食
属于杂食鱼，多数常见饵料都能接受。除了动物性饵料与干粮，需加入新鲜植物性食物或含植物成分的薄片。
习性与混养
只要水质不偏软酸，可与环境需求相合的其他卵胎生鱼、强健脂鲤及适当的小型鲶鱼混养。雄鱼会反复追逐雌鱼，宜每雄配数条雌鱼，以分散压力。
雌雄区分
雄鱼略小、颜色更鲜艳，臀鳍形成交接器，并在成熟后形成特征性的隆背；雌鱼没有同样明显的雄性体形。
繁殖
通常很容易繁殖，妊娠约 6～8 周，每胎可达约 50 条。成鱼会捕食后代，可将孕鱼移入独立缸，产后再移回。繁殖网盒或小型隔离盒空间太小，不宜作为育苗缸。
鱼苗出生即可吃丰年虾无节幼体或粉碎薄片，喂养良好时可在不到 6 个月内达到成鱼大小。有说法认为温度可能影响性别比例，较高温度下雌鱼更多，但这不是已经确定的控性方法，也不应因此超出适用温度范围。
补充说明
成年雄鱼的隆背来自脂肪组织，并非单凭这个外形就能判断脊柱畸形。

Overview
Mature male Limia nigrofasciata develop a conspicuous back profile through fatty tissue deposited along the spine. This readily bred livebearer suits a planted aquarium with open swimming areas, provided soft, acidic water is avoided.
Distribution & habitat
Its range covers Haiti and the Dominican Republic. Large groups use shallow, heavily vegetated water, and brackish populations occur at several localities.
Aquarium setup
A tank around 45 cm long and 41 L provides a starting point. Combine plant thickets with open space. Although decoration is not demanding, females benefit from retreats out of sight of males.
Diet & feeding
Most aquarium foods are accepted by this omnivore. Include fresh plant material or vegetable-based flakes alongside other preparations and animal foods.
Behaviour & compatibility
A community is possible in suitably hard, nonacidic water. Other livebearers, robust characins, and appropriate small catfishes are potential companions when their requirements match.
Persistent male courtship can burden females. Maintain several females for each male and provide dense cover.
Sexual dimorphism
Males are slightly smaller, more colorful, and equipped with a gonopodium. The characteristic hump develops as they mature.
Breeding
Propagation is generally straightforward. Pregnancy lasts roughly six to eight weeks, and broods approaching 50 young are not unusual. Since adults eat offspring, move a gravid female to separate quarters and return her after delivery. Small breeding traps or net boxes lack adequate growing space.
Newborns accept Artemia nauplii and crushed flakes. With good feeding, adult size may be attained in under six months. Temperature has been suggested as a possible influence on sex ratio, with warmer conditions yielding more females; this remains a suggestion rather than a dependable sex-control method and does not justify exceeding the established temperature range.
Notes
The adult male's raised back results from fatty tissue. That outline alone should not be interpreted as a spinal deformity.
