概述
假锉甲鲶（Rineloricaria fallax）是温和少动的鞭尾型异型，适合安静群体饲养。它不适应长期较高水温，挑选伙伴时不仅要看性格，也要匹配温度要求。
分布与栖息地
原生圭亚那与巴西的鲁普努尼河上游和布朗库河水系，常生活于浅而有流动水的沙底落叶层。
饲养环境
参考约 90 × 30 × 30 厘米，沙底铺落叶，配枝木和平滑石块。石洞、木洞或小管可作繁殖位置，水草缸也可，但避免强光。
食性与喂食
以附着生物和小型甲壳类为天然食物，缸内杂食，喂下沉干粮、蔬菜及小型活冷冻饵。
习性与混养
适合小群，与安静温和鱼共处。过分活跃或好斗的伙伴会使它躲藏并抢走食物；一般只有繁殖时才出现领地行为。
雌雄区分
成年雄鱼头部与胸鳍出现齿状棘，雌鱼缺少。
繁殖
成鱼状态合适时较易产卵，育苗更需耐心。可从六尾以上幼鱼获得配对，软略酸水配小于约 5 厘米直径的管洞。雄鱼清洞、雌鱼入内产卵后，由雄鱼受精并独自照料。可移出其他鱼或连管洞一起转缸，约四至五天孵化，再二至三天自由游动后移开雄鱼。幼鱼需随时有柔软蔬菜、藻膜及微虫或初孵丰年虾，并每天少量换水。难以启动繁殖时，可尝试偏凉水换约 50%～70%。

Overview
Peaceful and largely inactive, Rineloricaria fallax suits a quiet group arrangement. It does poorly at higher temperatures, so companion selection must account for its cooler requirements as well as temperament.
Distribution & habitat
It is native to the upper Rupununi and Branco basins in Guyana and Brazil. Shallow flowing water with leaves over sand is typical habitat.
Aquarium setup
An aquarium around 90 by 30 by 30 cm can be arranged with leaves over sand, branches, and smooth rocks. Rock or wood cavities and tubes provide breeding sites. Plants can be used while retaining subdued illumination.
Diet & feeding
It naturally grazes surface communities and small crustaceans. Aquarium feeding is omnivorous: combine sinking prepared foods, vegetables, and suitable small live or frozen supplements.
Behaviour & compatibility
Keep a small group with peaceful, restrained companions. Vigorous or aggressive fishes can cause withdrawal and food deprivation. Territorial behavior is mainly limited to breeding.
Sexual dimorphism
Adult males develop odontodes on the head and pectoral rays, absent in females.
Breeding
Obtaining eggs is usually easier than rearing the fry. Start with six or more juveniles and provide narrow breeding tubes in soft, slightly acidic water. After the female lays in a cleaned cavity, the male fertilizes, guards, and fans the eggs alone. Separate other fish or move the occupied tube if needed. Eggs hatch after four to five days, and free swimming follows two to three days later, when the male can be removed. Keep soft vegetables, algae, and tiny live foods continuously available, with small daily water changes. A 50–70% cooler-water change may encourage reluctant breeders.
