簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 8; 背的軟條 (總數) : 7 - 8; 臀棘: 1; 臀鰭軟條: 7; 脊椎骨: 31. This species is distinguished from its congeners by the following characters: no head lateral line canals; scales only under pectoral; body of live breeding males with 10-15 dark, irregular bars; D1 7 rays, D2 8.5 branched rays, A 7-8.5 branched rays (Ref. 59043); interorbit with uniserial row of papillae flanking each orbit (Ref. 12215).
沒有頭部側線管; 具有側面每個眼窩的乳突的排成一列列的眼窩; 鱗片侷限於腋窩的小區塊了; D 17, D 2個 I/8. 雄性有一些縱帶, 改變色彩。
A short-lived species (less than 2 years) which occurs in small and karstic springs and streams, densely vegetated channels and slow-flowing streams (Ref. 59043); with constant water temperature, on sand or gravel with or without vegetation, also in silty areas, provided that the water remains clear (Ref. 26100). Feeds on small invertebrates. Spawns after first winter (February-July); females may spawn more than once during this season. Males defend the eggs deposited in cavities under stones, plant material or shells. Postlarvae pelagic. This species is threatened by water abstraction, which lowers the water table and habitat destruction caused by desiccation of some springs (Ref. 59043).
典型地出現於穩定的水溫與和緩的水流泉水中的一種生命期短的種, 在沙子或礫石上，有或者沒有植物的地方; 它也可能被發現於被提供水保持清澈的淤泥的區域。 吃無脊椎動物。 受到威脅的由於水資源減少與棲息地破壞.(參考文獻 26100)
