Description

The discus is a deep, strongly laterally compressed, disc-shaped cichlid from the Amazon basin in South America, especially the Rio Negro. The species grows to about 12 to 20 cm and has a round, silvery-brown to red-brown body with blue wavy lines over head and flank and nine dark cross-bars. It lives in calm, blackwater backwaters and flooded forests. Remarkably, the young feed for the first days on a mucus layer on the skin of both parents. It is one of the most prized aquarium fishes. The IUCN assesses the species as Least Concern (LC).
