一眉道人倒钩
The Puntius denisonii (Denison's barb, Red line torpedo barb, Roseline shark or Bleeding eye barb) colloquially and more popularly referred to as Miss Kerala is a Subtropical fish belonging to the Puntius (Barb) genus in the Cyprinidae (Minnow) family. It is endemic to the fast- flowing hill streams and rivers of the state of Kerala and South Karnataka in South India. They prefer a water temperature range of 20-25 degree Celsius and almost certainly live for over 8 years.The fish is characterized by a torpedo-shaped body with silver scales, a red line running from their snout, through the eye, back towards the middle of the body; and below the red line, a black line that runs the length of the fish to the tail. As they mature, a distinctive green/blue marking on top of the head develops. The fish attains a maximum length of 15 cm (6 in). They are active schooling fishes.Denison's Barb or Red line torpedo barb is endemic and exclusive to the Achenkovil and Chaliyar rivers. Specifically, they are found in four locations- Cheenkannipuzha (a major tributary of Velapattanam River), the Achankovil river, the Chaliyar river and near Mundakayam town. The species has an estimated range of 8'805 sq. km. P. denisonii is a benthopelagic species that is gregarious and shoals are known to occur in rocky pools with thick vegetation along their banks. They thrive in a subtropical climate in water with a 6.8–7.8 pH, a water hardness of 5–25 dGH and a temperature range of 20–25 °C

一眉道人倒钩,小时的个体除背鳍有少许的淡红外,其他身体部分偏素色,通常在超过5cm后开始出现红色及清晰的黑色条纹,体表的鳞片也随着成长呈闪光的银白色,黑色条纹从吻部贯穿眼睛至尾部,紧贴黑色条纹上方为宽长的猩红色条纹,同样从吻部上方贯穿虹膜直至腹鳍的正上方,犹如红色的眉毛,故也称红眉道人。
主要分布在亚洲印度南部的狭窄区域,个体天生胆小,群游性强,喜欢在日间活动,日常食谱相当广阔,几乎一点都不挑食。 即使在原产地也因为人口的增加和环境的污染而导致数目稀少。
对水的适应程度强。原生状态下栖息在以沙泥为河床的小溪的中、底部。
性情温和、胆怯,群游性特别强,喜欢在日间活动,特别适合草缸饲养,高耗氧,饲养时一定要保证水族箱内含有充分的氧气,不挑食,可喂于活体、干燥饲料、薄片等。
