概述
长丝拉蒙特甲鲶（Lamontichthys filamentosus）最醒目的是胸鳍和背鳍极长的丝状延伸。它虽并非罕见，却需要有经验者维持成熟、高氧且有充足藻膜的环境，不能放进刚开的洁净裸缸。
分布与栖息地
分布于巴西、秘鲁、厄瓜多尔及玻利维亚的亚马逊中西部流域。
饲养环境
长期饲养至少参考 120 × 45 厘米底面积。沙、砾石或混合底床上放不同大小圆石，使用大容量过滤，按需加造流和气石。光照应足以促进藻和附着微生物，避免新沉木大量释色削弱透光；老沉木较合适。附生耐流植物可增加遮蔽及长藻表面，裸露海绵也会成为刮食位置。
食性与喂食
接受优质干粮及少量动物性食物，但过高蛋白可能造成内部健康问题。可用植物比例较高的凝胶饲料，长期重点仍是持续获得成熟藻膜。主缸藻量不足时，可另缸强光培养长藻石，定期轮换入缸。
补充说明
标准体长超过约 6 厘米后，胸鳍硬棘可延成长丝，超过第一条分枝鳍条长度数倍；背鳍也有显著延伸。仅靠一般长尾或长鳍外观不能把所有近似异型视为本种。

Overview
Exceptionally long pectoral and dorsal filaments distinguish Lamontichthys filamentosus. Availability in the hobby does not make it easy: long-term care depends on a mature, oxygen-rich aquarium with abundant grazing surfaces, rather than a newly established bare display.
Distribution & habitat
It is native to the central and western Amazon basins of Brazil, Peru, Ecuador, and Bolivia.
Aquarium setup
Use at least a 120 by 45 cm footprint, with sand or gravel and rounded stones of varied sizes. Substantial filtration, supplemented by circulation and aeration where needed, keeps the water clean and oxygenated. Strong lighting should support algae and associated microorganisms. Aged wood is preferable to fresh pieces that darken the water and weaken illumination. Hardy attached plants and exposed filter sponges add usable grazing surfaces.
Diet & feeding
Prepared foods can supplement established grazing, and some animal items are accepted, but excessive protein may cause internal problems. Vegetable-rich gel foods are useful. Keep a dependable supply of algae-coated rocks and other mature surfaces. If the display cannot sustain enough growth, cultivate rocks separately under strong light and rotate them into use.
Notes
Above roughly 6 cm standard length, the pectoral spine develops a filament several times longer than the first branched ray, and the dorsal spine also extends markedly. These particular features are more useful for identification than simply labeling any long-finned loricariid as this species.
