简单描述
型态特徵 | 形态测量图
背棘 (总数): 8; 背的软条 (总数): 7-8; 臀棘 1; 臀鳍软条: 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).
没有头部侧线管; 具有侧面每个眼窝的乳突的排成一列列的眼窝; 鳞片局限于腋窝的小区块了; D 17, D 2个 I/8. 雄性有一些纵带, 改变色彩。
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).
典型地出现于稳定的水温与和缓的水流泉水中的一种生命期短的种, 在沙子或砾石上,有或者没有植物的地方; 它也可能被发现于被提供水保持清澈的淤泥的区域。 吃无脊椎动物。 受到威胁的由于水资源减少与栖息地破坏.(参考文献 26100)
