概述
黑腹泥鮰（Limia melanogaster）是牙买加特有的小型卵胎生鱼，性情温和，繁殖较容易。虽然个体不大，仍需要兼有草丛和开阔水域的缸，尤其应给被雄鱼追逐的雌鱼留下躲避空间。
分布与栖息地
仅原产牙买加，通常生活在小溪中。
饲养环境
缸长至少约 60 cm。密植区供躲藏，另保留充分游泳空间；浮水植物提供的遮蔽也有帮助。它适合硬水环境，挑选同伴时要同时考虑水质需求。
食性与喂食
对食物不挑剔，多数常见水族饲料均可接受。
习性与混养
总体温和，可与其他适应硬水的小型鱼相处。繁殖时雄鱼追逐雌鱼可能相当积极，因此不能只根据温和的总体性情忽略同种互动。
雌雄区分
雄鱼较小，臀鳍形成交接器。
繁殖
采用卵胎生方式，通常容易繁殖。繁殖缸宜尽量宽敞，设置密集草丛和浮水遮蔽，让雌鱼能够躲避追逐。
妊娠约 4～6 周，每胎约 20～50 条。相较许多其他卵胎生鱼，本种吞食后代较少，因此也可尝试在有遮蔽的原缸育苗。幼鱼出生即可吃刚孵化的丰年虾及粉碎薄片，但需要几个月才逐渐显出成鱼体色。
补充说明
旧资料可能把它列在 Poecilia 属下，现有名称使用 Limia。这种属名变化不代表可以买到两个独立物种；本种在普通观赏鱼贸易中仍较少见。

Overview
Endemic to Jamaica, Limia melanogaster is a peaceful small livebearer that is straightforward to breed. Its modest body size should not obscure its need for open swimming room and planted retreats, particularly for females pursued by males.
Distribution & habitat
Jamaica is its native range, where small streams are the usual habitat.
Aquarium setup
Use a tank at least about 60 cm long. Combine substantial open water with dense planted areas and some floating shade. Select companions that share its requirement for hard water.
Diet & feeding
It is an undemanding feeder that accepts most standard aquarium foods.
Behaviour & compatibility
Other small, hard-water-tolerant fishes are suitable candidates for a community. Males can nevertheless pursue females very energetically, so a peaceful general disposition does not eliminate the need to manage interactions within the breeding group.
Sexual dimorphism
The smaller male has a gonopodium formed from the anal fin.
Breeding
Livebearing reproduction is usually easy. Give the group as much room as possible, with thick vegetation and floating cover where females can escape persistent attention.
Pregnancy lasts approximately four to six weeks, with broods of about 20–50 young. Adults consume offspring less readily than many other livebearers, making rearing in the original planted aquarium an option. Newborns accept freshly hatched Artemia and crushed flakes, although adult coloration takes several months to develop.
Notes
Older publications may place this fish in Poecilia rather than Limia. Those historical combinations should not be mistaken for separate aquarium species. It remains an uncommon offering in general ornamental-fish stores.
