Apistogramma agassizii is one of the best known and widely kept dwarf cichlids. They are the type of both the agassizii group and complex of Apistogrammas. Apistogramma agassizii are found throughout the Amazon basin and have the largest geographic distribution of any Apistogramma species. They have been found in a variety of habitat types and water conditions.

Apistogramma agassizii was first described in 1875 from specimens collected in 1865-1866 by Professor J. L. R. Agassiz. They were first imported into Germany in about 1909 and have remained in the hobby since. This species has historically been one of the few Apistogrammas that has consistently been correctly identified by hobbyists.
Most of the Apistogramma species that were discovered early were kept and distributed under a variety of different names but agassizii have always been properly identified. This is probably due to the distinctively banded, spade shaped tail.
This female A.agassizii is in her brood colors. The black markings on the side of the female can change rapidly and combined with fin motions and swimming posture allows her to clearly communicate with her brood and other apistos.

Agassizii are typically dimorphic with the male being larger and more colorful. Females are a dull color that can range from gray to brown to dusky yellow until they put on their brood colors. At this time they become a vibrant yellow with a very contrasting black pattern that may appear as a stripe or as a single spot on their side. Apistogramma agassizii "Red Tail" is an aquarium strain that is the result of many selected breeding efforts.

There are many different forms of A. agassizii. Different geographic areas yield fishes in a variety of colors and patterns. Many of these are obviously agassizii while others seem to be different enough that they might be sub species or different species. There has been a lot of mixing of fish in the hobby and there are some very colorful aquarium strains that have been developed. 

Wild strains offer a beauty of their own and if you ever have a chance to acquire wild fish I encourage you to do so. If you do receive a wild strain and you have reliable collection locality you should take care to keep the strain pure, or to sell any offspring as an aquarium form if you breed them to other forms.

Apistogramma agassizii are found in a variety of waters in the Amazon. However, they Male A. agassizii cf. Rio Madiera generally do best in soft acid water, especially for breeding. They will do quite well in pairs but in a large enough aquarium you will experience harem breeding if you keep a single male with several females. Agassizii thrive on live foods but will adapt to many different foods in the aquarium. 

Apistogramma agassizii is one of the all time classic dwarf cichlids and if you ever have a chance, get some. You will find them to be great aquarium fish in a species tank or in the community aquarium.

尾鳍箭头状,外缘白色,变异种和人工培育的类型较多,如白尾型、蓝尾型、红尾型等。
  鱼体体侧一有条黑色纵斑,由眼睛基部一直延伸至尾柄前,在尾柄前端会有一个黑斑点,尾鳍为茅状尾,上有V字型的斑纹。为南美短鲷种类最多的一属,不同地域的鱼的产量,颜色和图案都不同,只用阿卡西来界定这个物种是不够的,他们很多显然是不同的亚种,甚至是不同品种,目前已经发现不下六十多种的同类变异型品种。在不同的亚马逊水域都能找到他们,但是最好用酸性软水饲养它们。较常见的品种有:野生阿卡西、黄尾、红尾、白尾等自然型等等,大多数是没有经过人工筛选育种;价位再高一点的就是经过颜色体型的筛选,经人工育种配对而繁殖出颜色鲜艳的子目代,例如目前水族市场上所见的超红尾阿卡西、双红尾阿卡西等等;还有一种就是较稀有的品种,如阿莲卡阿卡西、泰菲阿卡西等等。 在选购阿卡西短鲷的时候,除了观察它们的游姿、体色是否正常之外,还要注意体型上的选择,驼背、脊柱弯曲或尾鳍下垂的阿卡西短鲷个体就要尽量避免挑选。
