Distichodus sexfasciatus


Distichodus sexfasciatus
Six Banded Distichodus
短鼻六间鱼
This is the most common of the few Distichodus species regularly seen in the hobby, and sadly, it is often sold as being suitable for the general community tank. This is clearly not the case in terms of both its temperament and potential size. It is usually seen for sale at a couple of inches long, and at this size is a very attractive orange and black striped fish with bright red finnage. 

体椭圆型,背部具一黑色小脂鳍。头部较小,吻部稍尖。幼鱼鱼体呈橘色,身上具六道明显黑色横纹延伸至腹部,成鱼的体色则较深褐色,黑横纹也较不明显呈灰色。
属于中底栖性之热带淡水鱼类。游泳能力佳,在河川或湖泊的浅水域中活动。属杂食性鱼类,喜好吃食甲壳类、昆虫、蠕虫及植物碎屑。
以中性水质饲养为宜,虽然在过于酸性下的水质虽也能生存,不过显现不出漂亮的颜色及光泽。若长期不换水,每当水变成酸性时,似乎就会发生「缺乏碘」的现象。且皇冠九间身长超过30公分时,「缺乏碘」的现象会令其下颚处,将垂挂着肉瘤般的肉片不美观,因此在滤材中放入些许的珊瑚应该可让PH稳定。
皇冠九间的即使长大后也不食用小鱼,就是这种鱼的特性,因此即使是与日光灯、孔雀混养也不会有被吞食的危险。
