Description: Adult fish have a greenish blue shine over the body, with a large back blotch from the gill cover to the caudal fin base.
Care: Not too difficult. Larger tanks are required. A lot of driftwood, some (fast growing) floating plants to reduce the light. A thick layer of large gravel, good filtration, best over peat. Water neutral to slightly acidic, and not too hard. The fish can well be kept with discus fish.
Feeding: Omnivorous, flake, frozen and live food are accepted. Plants are part of their diet!
Size:Up to 30 cm
Breeding: Sometimes described as quite difficult, whereas others report it as being easy. The fish seem to spawn in hard water as well as in soft acidic water. In to hard water the eggs do not hatch. pH best neutral or slighly acidic. The parents deposit the eggs on stones, if a vertical one is available it is usually preferred, but in the absence of a vertical stone they will also spawn on horizontal surfaces. The fry are tiny, and difficult to raise.
Sexual dimorphism: Dorsal and anal fin are more pointy in males
Additional: A new form or species has been imported recently, and is sold as Uaru sp orange
