背棘 (總數) : 2 - 3; 背的軟條 (總數) : 7 - 9; 臀棘: 3; 臀鰭軟條: 10 - 13; 脊椎骨: 36 - 42. Diagnosed from other cyprinids in central and eastern Europe by having incomplete lateral line with about 8-12 pored scales, keel covered by scales between pelvic origin and anus, mouth superior, and 11-13½ branched anal rays (Ref. 59043). A small fish with large silvery scales and an inconspicuous intense silvery band along each side. Lateral line incomplete, sometimes absent, with perforated scales. Anal fin longer than dorsal fin. Mouth turns upwards. The lower edge of the body between the pelvic fins and the vent forms a sharp keel. The scales are very loosely attached and fall away if the fish is handled. Also Ref. 40476.
一種小的魚具有大的銀色鱗片與一條不明顯的密集銀色的條紋沿著兩邊。 側線不完全的, 有時不存在, 藉由有排孔的鱗片。 臀鰭長度超過背鰭。 嘴變向上的。 在腹鰭與排洩孔之間的身體的下面邊緣形成一個銳利的龍骨脊。 鱗片非常鬆弛地被附上而且秋天之久，如果魚被觸摸。 也參考文獻 40476.
Inhabits lowland riverine habitats especially oxbows and other water bodies only connected to rivers during floods. Often encountered in ponds, steppe lakes and small water bodies not connected to rivers (Ref. 59043). Occurs in large schools which are most numerous in autumn. Found between weeds in shallow pools and creeks, shallow lakes, peat and clay excavations and canals. It is exposed to the stormy flow of water (in spring, autumn and winter), but usually choose quite places like small bays, plots behind bottom stones extending out of water and concrete foundations of bridges. In autumn, the schools of fish keep to the surface and rarely go to the pelagic zone. Towards winter, the schools break up and the number of fish per unit of river square decreases rapidly (Ref. 27674); they spend the winter in deeper waters (Ref. 41592). Feeds on phytoplankton and zooplankton and on flying insects (Ref. 27368). Spawns among vegetation (Ref. 30578). Aquarium keeping: at least 10 individuals; minimum aquarium size 100 cm; not recommended for home aquariums (Ref. 51539). Scales were utilized for production of Essence d'Orient, which was used for coating artificial pearls. Locally threatened due to draining of wetlands. Reaches up to about 9 cm SL (Ref. 59043).
形成大群的魚群最多的秋天時。 在水淺的水池與小溪，淺的湖泊，泥炭洞穴與管中發現在雜草之間了。 它是暴露於水 (在春天, 秋天與冬天) 的猛烈的水流, 但是通常選擇平靜的地方像小海灣, 計畫翻譯延伸到水與橋基外面的在後底部的石頭。 秋天時，魚群保持在水面而且很少地去到大洋性區域。 快到冬天時，魚群消失與快速地魚的數目河中每單位面積減少;(參考文獻 27674) 他們在較深的水域中度過冬天。 (參考文獻 41592) 吃浮游植物與浮游動物與吃會飛的昆蟲。 (參考文獻 27368) 繁殖發生於四月到五月, 在植物之中。 產卵被由雄魚保衛.(參考文獻 30578) 水族館保持: 至少 10個個體; 水族館最小體型 100 公分; 不向那邊推薦家庭的水族箱魚。 (參考文獻 51539)
Territorial males clean the spawning sites and guard the eggs which are attached in strings around roots, reeds, aquatic vegetation or any material drifting on the water surface (Ref. 59043). When males tend the clutch, which is usually located on the stem of a water plant, they provide the clutch with fresh water by nudging the water plant. In addition, they spread an anti-bacterial fluid over the eggs (Ref. 1672). If possible, some fish will enter streams for spawning.歐洲與亞洲。 透過管道系統進入北歐之內散佈開了。 在伯恩公約的附錄 3 中 (受保育的動物群).
