Discus (Symphysodon spp.) are a genus of three species of cichlid freshwater fishes native to the Amazon River basin. Discus are popular as aquarium fish and their aquaculture in several countries in Asia is a major industry Discus belong to the genus Symphysodon, which currently includes three species: The common discus (Symphysodon aequifasciatus), the Heckel discus (Symphysodon discus), and a new species which has been named Symphysodon tarzoo. However, a further investigation published in August 2007 suggested that the genus held the three species: S. aequifasciatus (the green discus), S. haraldi (the blue/brown/common discus) and S. discus (the Heckel discus). Both studies suggest three species; the only disagreement is in the scientific names for each.Like cichlids from the genus Pterophyllum, all Symphysodon species have a laterally compressed body shape. In contrast to Pterophyllum, however, extended finnage is absent giving Symphysodon a more rounded shape. It is this body shape from which their common name, "discus", is derived. The sides of the fish are frequently patterned in shades of green, red, brown, and blue. The height and length of the grown fish are both about 20 cm Symphysodon species inhabit the margins of floodplain lakes and rivers in the Amazon Basin of lowland Amazonia, where its is part of the highly diverse Neotropical fish fauna.
The three species of Symphysodon have different geographic distributions. S. aequifasciatus occurs in the Rio Solimões, Rio Amazonas and the Río Putumayo-Içá in Brazil, Colombia and Peru. In contrast the distribution of S. discus appears to be limited to the lower reaches of the Abacaxis, Rio Negro and Trombetas rivers. S. tarzoo occurs upstream of Manaus in the western Amazon

七彩神仙鱼、又名亚马逊河燕鱼盘丽鱼(Symphysodon acquifasciatus),分布于南美洲亚马逊河流域和秘鲁、巴西、圭亚那体长可达20厘米。体近圆盘形,扁平。体色丰富多变,有以红色为主基调的红七彩,以棕色为主基调的棕七彩,以蓝色为主基调的蓝七彩,并以红、黄、蓝、绿、黑、棕、白、紫色等为点缀,花色繁多,美不胜收,素有“热带鱼王”的美称。与其他鱼相比不易伺养。宜用大型水族箱(长度在90厘米以上),箱中最好种上疏密相当的水草,放置几块岩石,为其创造一个幽静舒适的生活环境。
  据有关资料记载,七彩神仙按照海克-布列罕先生所倡导的分类方法,分为野生七彩和人工育种七彩两大品系。其中,野生七彩有野生黑格尔七彩、野生棕七彩、野生蓝七彩、野生绿七彩;人工育种气彩有条纹蓝绿七彩、纯蓝绿七彩、红蓝绿七彩、红色型七彩和其它七彩。 野生黑格尔七彩的主要特征:体侧有的很明显地或隐隐约约地分布9条垂直黑争条纹,其中第1、第5、第9条黑带较明显,尤其是第5条黑带又宽又粗,称“黑格尔条纹”;野生棕七彩的主要特征:体表也有9条若隐若现的垂直黑带,但黑格粗细色彩一致;野生蓝七彩的主要特征:体色主基调褐色、灰褐色或红棕色,背鳍和腹鳍上有蓝色条纹,头部和背部也有蓝色条纹,体侧黑带不明显;
  野生绿七彩的主要特征:体色主基调淡褐色或红棕色,臀鳍上有红色斑点,后半身下缘部位有或泞的蓝色。育种条纹蓝绿七彩的主要特征:体色主基调红色,体表有蓝绿的条纹或点纹;育种纯蓝绿七彩的主要特征:体表布满蓝绿色纹;育种红蓝绿七彩的主要特征:体色主其调红色,并在体表缀有蓝色或绿色的条纹和斑点;育种红色型七彩的主要特征:体表布满鲜红色的条纹,几乎没有其他色彩出现。
