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。
初熟時的長度 / 大小 / 重量 / 年齡
成熟度: Lm 6.1, range 6 - 6.4 cm
Max length : 7.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 59043); 13.0 cm SL (female); 最大年齡: 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).
一種生命期短的種。 成魚棲息於中下游, 藉由淺水域，砂質底部與水下的廠。 (參考文獻 11240) 捕食無脊椎動物與植物。 產卵於五月到七月中。 卵生的, 在繁殖的時候有明顯的成對。 (參考文獻 205) 受到威脅的由於污染，棲息地破壞與其他魚種的引入.(參考文獻 26100)

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。
