Etymology: Nannostomus: Latin, nannus = small + Greek, stoma = mouth (Ref. 45335).
Eponymy: F J B Beckford (1842–1920) of Winchester was a naturalist and one of the early bee-keepers in Hampshire. He presented the pencilfish holotype to the BMNH, it being part of a collection he had made on the coast of Demerara, British Guiana (Guyana). (Ref. 128868), visit book page.

Taxonomic Remarks
The most recent distributional records were published by Weitzman & Weitzman (1982: Fig. 229). Most recent systematic description by Weitzman (1966). Commonly exported as an aquarium fish since 1910, Stansch (1914). The courtship and other behavior was studied in detail by Caplan & Dunham (1978) and Kuenzer (1982). Probably introduced into rio Jaquraipe, east of Salvador, Bahia Brazil, Géry (1977) and definitely introduced into baía de Guanabara, Rio de Janeiro, Bizerril & Lima (2001). This species is commonly exported as an aquarium fish from Peru and Guyana.

大小 / 重量 / 年齡
Inhabits small rivers with little current and in swamps where they are very common. Forms groups where the males dominate to defend their territory. Is highly appreciated by aquarists (Ref. 12225). Feeds on worms, crustaceans and insects (Ref. 7020). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).
棲息於小的河水流很少的地方與在沼澤中在那裡它們非常普遍。 聚集族群雄性佔優勢防護他們的領土的地方。 高度地被獲得水族館賞識.(參考文獻 12225) 吃蠕蟲，甲殼動物與昆蟲。 (參考文獻 7020) 水族館保持: 形成 5個或更多個體的群體; 水族館最小體型 60 公分.(參考文獻 51539)

生命週期和交配行為 成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
At spawning time in captivity, male and female swim alongside one another. Several batches of 1 to 5 eggs are laid among the fine-leaved plants, with a total of up to 200 eggs in some cases; eggs hatch in 30 to 40 hours and fry are free-swimming about six days after (Ref. 7020). Between 24°-27°C, eggs hatch in 24 hours (Ref. 205).南美洲: 在蓋亞那的河的本地種南至亞馬遜河流域並且向上到亞馬遜河到尼格羅河。
