Apistogramma cacatuoides is a species of South American cichlid usually known under the common name cockatoo dwarf cichlid. Unlike many other Apistogramma species, A. cacatuoides is not threatened by extinction, as it is widely bred in captivity for the aquarium trade.The male cockatoo dwarf cichlid reaches a body length of 8 centimetres. The female is considerably smaller, reaching only 5 centimetres. The body shape is long and of middle height and the mouth is rather big with thick lips. The male is more colorful than the female, usually with red/orange dorsal and caudal fins. The leading 3 or 4 hard rays are elongated, and the ventral fins are clear. In color, the female is quite dull but with a clear black line running along her flanks. Her background color is a pale yellow, but this will become vibrant when mating or brood protecting. In addition, she lacks the elongated dorsal rays of the male and her ventral fins show a black leading edge. There are several color forms which naturally occur in the wild; these include blues, yellows and some reds. Because of selective breeding the colors are now much more pronounced. Both sexes have a dark line leading from the eye to the bottom of the gill flap.The cockatoo dwarf cichlid is found in the Amazon River basin, in tributaries of the Ucayali, Amazon and Solimões rivers from the Pachitea River to Tabatinga in Peru and Colombia where it lives in small shallow streams or lagoon-like waters in the rain forest. The fish prefer a water temperature between 24 and 28 °C. The bottom of these waters is covered with leaves that are used by the fish for hiding.
The cockatoo dwarf is one of the best suited cichlid species for the planted aquarium. But because the male is highly territorial, the fish should be kept in pairs, trios (one male with two females), or harems (one male with many females), and in the company of peaceful tankmates like tetras.
Water conditions should be maintained in the pH 6.5-pH 7.0 range. These are one ofe the few South American Dwarf Cichlids that can tolerate alkaline water.

凤尾短鲷体型修长,在成熟雄鱼的背鳍有6根硬棘,口器宽大,背鳍呈琴弦状,在背鳍的末端及尾鳍会有橘红色的斑点分布,尾巴为凤尾,故因而被称为凤尾短鲷。像大多数短鲷一样凤尾短鲷的公鱼和母鱼的外观差别很大。它们是相对容易繁殖的短鲷品种。虽然他们会不时地与同种或异种鱼支争斗,仍尚不致置对方于死地。喜爱弱酸性至中性的软水,肉食性。
  公鱼体长可达8厘米,有丰富的色彩,他们通常有非常高的背鳍和天线。从色彩上分为红色,超红,橘色。花色上有全花,半花等。母鱼比公鱼小很多,大概只有5厘米左右。她们的颜色通常为褐色或者暗黄色,但是在发情期会有鲜艳的黄色身体。
  凤尾短鲷基本上能够忍受中等硬度和ph7的水质,平时水温应当保持在24~26度之间。数据表明,从幼鱼孵化后的3个月将水温保持在24度左右,能够繁殖出公母比例最平衡的幼鱼。
  最佳条件PH:6.5 硬度:6 温度:26c 鱼缸体积:40升
  喜欢活食,卵生,适合有水草和沉木的水族箱,鱼缸中可添加榄仁叶,可调节水质,还可以预防疾病,任何的短鲷如果想养得到最美丽的状态,最好不要混养。
