Europe: Iberian Peninsula, except in Alagon system (Tagus drainage), northern Ebro and northern Douro drainages. Also found north of the peninsula where it has been locally introduced.
歐洲: 葡萄牙與西班牙。
首次成熟时的长度 / 大小 / 重量 / 年龄
成熟度: Lm 6.1, range 6 - 6.4 cm
Max length : 7.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 59043); 13.0 cm SL (female); 最大年龄: 5 年 (Ref. 38442)
Presence of mandibular barbel 4-8 times in HL. Pectoral fin length 4.3-5.4 times in SL in males, 4.3-9.0 times in females. 6-7.5 branched dorsal rays. One lamina circularis.
Body shape (shape guide): elongated.
A short-lived species, secretive in nature (Ref. 38442). Adults inhabit middle and lower reaches, with shallow waters, sandy bottoms and submerged plants (Ref. 11240). During dry periods, they can survive in very small water bodies (Ref. 59043). Feed on invertebrates and plants. Spawn in May to July. Oviparous, with distinct pairing during breeding (Ref. 205). Eggs are small (1.7 mm) and sticky, placed within dense vegetation if available (Ref. 59043). Threatened due to pollution, habitat destruction and the introduction of other species (Ref. 26100).
居住于中下游的一种生命期短的种, 与浅水域,砂质底部与水下的厂.(参考文献 11240) 吃无脊椎动物与植物。 五月到七月时产卵。 受到威胁的由于污染,栖息地破坏与其他鱼种的引入.(参考文献 26100)
生命周期和交配行为

During courtship, 'the male follows the female and, after both enter dense vegetation (e.g. filamentous algae), the male forms a complete ring around the female's body behind the dorsal as the female releases the eggs' (Ref. 59043).歐洲: 葡萄牙與西班牙。
