三角慈鲷
Uaru amphiacanthoides, whose common name is the Uaru, is one of the medium to large New World Cichlids. There are actually two species of Uaru, Uaru amphiacanthoides and the Uaru imperialis, both rarely exported. This article will concentrate on the former and the more common. Although the Uaru can attain sizes up to 12 inches or so, it is rare to see one over 10 inches. The coloration of the adult Uaru is rather bland. They are greenish brown with a little black along their sides. But when spawning time comes along they color up magnificently. The whole sides of their bodies turn black leaving just a little brown around the edges and their eyes brighten to a coppery red color as if someone turned on a light inside their heads. Their young are a beautifully mottled version of their parents but lose this coloration around the 3-4 inch size.

黑云的学名叫三角鲷。原产于亚马逊河、圭亚那。体长25cm,ph6-7.0 gh5-10,是比较早的引进品种,对水质要求很苛刻,南美大型慈鲷一般都是较为凶残的鱼种,黑云却是个例外,生性高雅,黑云体形侧扁成卵形,有些类似菠萝但是又偏长,越大越明显;黑云的眼相对于头的比例来说要比菠萝大;二者嘴的构造也不同,相对于菠萝来说,黑云的嘴更强健且突出。黑云是一种越大越好看的鱼,小的黑云全身黑色,身上还有很多白色斑点,特难看。但长到10厘米以后情况开始好转,体表基色向柠檬黄色转变,身体中间出现黑斑,眼圈开始变红,最后体表基色接近暗蓝色,有代表性的一块三角形黑斑形成。黑云的饲养很容易,什么都吃,可谓是热带鱼中的食神,是一种适合混养的好鱼。
  雄性的黑云体色较雌鱼更加艳丽,体形稍大于雌鱼,背鳍和臀鳍较长雌鱼腹部膨胀。黑云的繁殖比较困难,这也是其价格比较高的原因,此种于是又母体产生的体液喂养幼体,详细请查阅七彩神仙相关资料。
