概述
莫氏锉甲鲶（Rineloricaria morrowi）来自秘鲁乌卡亚利河，贸易中比某些近缘鞭尾型异型少见。它温和而少动，在有落叶和洞穴的安静环境中较容易正常摄食与活动。
分布与栖息地
原生秘鲁乌卡亚利河流域，常利用沙底上的落叶层。
饲养环境
参考约 90 × 30 × 30 厘米。沙底散布落叶，放入枝木和平滑石块，石木洞或小管作为潜在产卵处。弱光比强照明更合适，也可置于有充分遮蔽的水草缸。
食性与喂食
天然取食附着生物和小型甲壳类，在缸内表现杂食，接受下沉干粮、蔬菜及小型活冷冻饵。
习性与混养
小群较合适，与温和小鱼或安静鲶鱼搭配。过强伙伴会令它退缩并在食物竞争中落后，领地表现主要出现在繁殖时。
雌雄区分
成熟雄鱼头部和胸鳍棘有齿状突起，雌鱼缺少。
繁殖
繁殖方式与同属相似，可从六尾以上幼鱼取得配对，提供软略酸水和直径小于约 5 厘米的管洞。调理后雄鱼清理洞穴，雌鱼入洞产卵，雄鱼随后受精、扇水并护卵。约四至五天孵化，再二至三天自由游动后可移开雄鱼；也可隔离其他鱼或转移整根管洞。幼鱼不断获得柔软植物饵和藻膜，并辅微虫、丰年虾幼体，配每天少量换水。若迟迟不产，可尝试偏凉水换约 50%～70%。

Overview
Less commonly encountered than some relatives, Rineloricaria morrowi is a quiet Peruvian whiptail from the Ucayali drainage. A sheltered aquarium with leaves and cavities supports feeding and settled behavior without pressure from vigorous companions.
Distribution & habitat
It inhabits the Ucayali basin in Peru, usually among leaf litter over sand.
Aquarium setup
Use an aquarium around 90 by 30 by 30 cm. Sand and scattered leaves can be combined with branches, smooth stones, and small cave-like shelters. Low lighting is preferable; a planted tank also works if cover is plentiful.
Diet & feeding
Its natural feeding includes surface growth and small crustaceans. In captivity, offer a mixed diet of sinking prepared foods, vegetables, and appropriately small live or frozen items.
Behaviour & compatibility
Keep a small group with quiet, peaceful companions. Strong competitors can cause withdrawal and poor food access. Territorial behavior occurs mainly during breeding.
Sexual dimorphism
Adult males develop head and pectoral-spine odontodes, absent in females.
Breeding
Breeding follows the same broad cave-spawning pattern as its relatives. Start with six or more juveniles and supply narrow tubes in soft, slightly acidic water. A male cleans the site, then fertilizes and tends eggs laid by a visiting female. Hatching takes four to five days, followed by free swimming two to three days later, when he can be removed. Other fish or the occupied tube may be separated to reduce predation. Fry need continuously available soft greens and algae, supplemented with microworms or nauplii, plus small daily water changes. A 50–70% cooler-water change may encourage spawning.
