概述
艾氏锉甲鲶（Rineloricaria eigenmanni）是较常见的鞭尾型异型，尾柄横带环绕到腹面、各鳍也有条纹，是重要辨认组合。它平时温和少动，状态良好时较容易产卵，但幼鱼不能缺食。
分布与栖息地
分布于哥伦比亚和委内瑞拉，多在沙底落叶层间生活，清水与富含悬浮泥沙的白水环境均有记录。这里的白水不指急流白浪。
饲养环境
参考约 90 × 30 × 30 厘米，沙底散落枯叶，配枝木、圆石和石木洞穴或小管作产卵处。密植缸也可，但应避免很强光照。
食性与喂食
天然取食附着生物及小型水生甲壳类，缸内杂食。下沉干粮、菠菜、西葫芦、羽衣甘蓝等植物食物，与红虫、水蚤等活冷冻饵搭配。
习性与混养
小群饲养较合适，除繁殖时外一般不争地盘。伙伴可选小型温和鱼或安静鲶鱼，避开强势争食者，否则它容易退缩并吃不饱。
雌雄区分
成熟雄鱼头部及胸鳍鳍条长有齿状棘，雌鱼没有。
繁殖
可养六尾以上幼鱼自然配对，软而略酸的水中提供直径小于约 5 厘米的管洞，用植物饵与活冷冻饵调理。雄鱼选洞清理，雌鱼产卵后离开，雄鱼受精、护卵和扇水。可移开其他鱼，或把管洞整体转至育苗缸。约四至五天孵化，再二至三天自由游动，此时可移开雄鱼。幼鱼需持续获得柔软植物材料、长藻石与微虫或丰年虾幼体，每天少量换水；迟迟不产可尝试偏凉水换约 50%～70%。

Overview
Tail-peduncle bands that continue around the underside, together with barred fins, help identify Rineloricaria eigenmanni. This quiet whiptail can breed readily in suitable conditions, but raising its offspring requires dependable food and water maintenance.
Distribution & habitat
It comes from Colombia and Venezuela, living among leaves over sand in both clear and sediment-rich white waters. “Whitewater” here refers to sediment, not turbulent rapids.
Aquarium setup
An aquarium around 90 by 30 by 30 cm can suit its low activity. Scatter leaves over sand, adding branches, rounded stones, and caves or tubes. A planted aquarium is also suitable if lighting is subdued.
Diet & feeding
Natural feeding includes surface growth and small crustaceans. In captivity it is omnivorous, taking sinking prepared foods, vegetables, and small live or frozen invertebrates. Rotate these components rather than using a single food.
Behaviour & compatibility
A small group suits it well. Territorial behavior is mainly associated with spawning. Quiet small fishes and compatible catfishes are better companions than vigorous feeders, which can intimidate it and monopolize meals.
Sexual dimorphism
Males develop head and pectoral odontodes at maturity; females lack them.
Breeding
Raise six or more juveniles to obtain a pair. Supply narrow tubes under about 5 cm across in soft, slightly acidic water and condition breeders with greens and invertebrates. The male cleans a cave, fertilizes deposited eggs, and alone guards and fans them. Remove other fish, or transfer the occupied tube, to reduce fry predation. Hatching takes four to five days, with free swimming two to three days later, when the male can leave. Provide constant access to soft plant foods, algae-coated rocks, and tiny live prey. Small daily water changes support the sensitive fry. If spawning stalls, a 50–70% cooler-water change can be tried.
