Copadichromis borleyi is a species of cichlid fish endemic to Lake Malawi in East Africa. The species is popular in the fishkeeping hobby where it is frequently kept in aquariums. The species has numerous common names used in the ornamental fish trade including: 'Redfin Hap' (or "Happy" or "Haplo") and 'Goldfin Hap'.C. borleyi is a relatively small cichlid, males grow to 12-14 centimetres total length, while females are typically slightly smaller reaching 11 centimetres. In addition to these minor difference in size, the species displays marked sexual dimorphism with males displaying larger ventral fins marked with egg spots, light-blue edging to the dorsal and ventral fins, along with metallic blue colouration of the head, and yellow to red flanks. In contrast, females are silver-to-brown and display three black spots along their sides. Juveniles are monomorphic and are coloured like the adult females. Some intraspecific variation has been recorded with regard to colouration, these differently coloured forms are geographically restricted to certain localities in Lake Malawi.C. borleyi is widespread in Lake Malawi, occurring along the coasts of Malawi, Mozambique and Tanzania. The species is limited to littoral zones with large rocks and boulders. The water in which species is found is warm (24 – 28 °C,), hard and alkaline; typical of the water chemistry of Lake Malawi.The species was described in 1960 by Thomas Derrick Iles as Haplochromis borleyi, and was later moved to Copadichromis by David Eccles and Ethylwynn Trewavas. The species is also known under the synonym Cyrtocara borleyi, and is occasionally sold under the trade name of Haplochromis granderus.


Copadichromis borleyi "Mbenji"(Mbj波里尔)是血艳红另外的一种地域型。血艳红产自马拉维湖的Kadango,而Mbj波里尔却产自Mbenji或者Namalenji岛。由于Mbj波里尔的习性非常的温和,而且成鱼胸鳍会拉长得非常的漂亮,所以这鱼现在比血艳红受大家欢迎。这个鱼的头部和背鳍是蓝色、侧面部是黄色。
  另外血艳红、Mbj波里尔等鱼还有其它的几种地域型,背鳍的基底部变蓝色的,或者全身变得金属蓝色的等等地域型。
  总的现象是越北越黄,越南越红或蓝的情况。单独饲养这种鱼混养的话非常容易繁殖,但是最好是鱼缸里面放一些石头让雌鱼躲藏,以免受到外界惊吓。成鱼最大体长18公分左右。
  Copadichromis borleyi在爱好方面是比较相同的, 或许已经收集了许多不同的差异。与Kadango的不同就是这个独特的“红色的鳍” C. borleyi 的" 红色鳍" 也是从Tawain 礁石 , Mbenji 海岛, Nkhungu 礁石, 和Ntekete收集来的。每个地点都有轻微的张力, 引人注目的特征。这个种类另一个普遍的差异是Copadichromis borleyi " 金色的鳍", 这方面的不同是雄鱼是黄色的身体代替了橘黄色。C. borleyi也可以由它的长的腹鳍来区分。许多不同的有比其他更长的腹鳍,当缩拢时,长的腹鳍可以扩展到他们的身体那么长。 只有雄鱼有亮丽的颜色,雌鱼是带有橘红色鳍的黑色的身体。C. borleyi是Utaka类的最大的之一。雄鱼可以达到6到7英寸的长度,而雌鱼要小一些。不同地方的雌鱼在外表上大多数是不同的。许多雌鱼都非常的黑,而有一些却更趋向于银色。现在,我有4条野生的雌鱼和1条野生的雄鱼。当拿回这些鱼时,它们的颜色都很深,缺乏一些颜色。事实上,如果不看它们鳍的形状,雄鱼和雌鱼是很难区分的。一星期后,雄鱼开始变得亮丽起来,它的蓝色和橘色已经重现了。大约在3星期后,它3次产卵。这5条鱼经常在一起游。雄鱼对雌鱼比较温和,很少看到它们攻击雌鱼或是水族箱中其他的伙伴,除了在繁殖期,它们会防御侵入到它们领土的入侵者。它们每次产卵的地方不是固定的,它们每次都会选择一个新的地方,但是它们一般会选择一个贴近石头的地方。
  孵化过程要持续超过3星期的时间。鱼苗已经显现除深灰色的身体和黄色或橘黄色的鳍,这个是依靠它们地区上的血统
