Found in Asia, known only from Lake Holmes (Danau Bira) in the lower Mamberamo River system in Irian Jaya, Indonesia.[1]


Mature females will be smaller than mature males. Mature males will have a distinctive longer first dorsal fin which overlaps the second. The males body will become deeper as he ages and his forehead will become more sloped and indented.


Bleher's Rainbowfish will readily breed in the home aquarium when two fish of the opposite sex are kept together. The fry require the typical high care level of most fish fry, including regular feedings of infusoria or vinegar eels until they have grown large enough to eat prepared foods.

Tank compatibility[edit]

A peaceful shoaling fish, excellent for the larger community tank, keep in groups of 5 or more, with at least 2 females per male. Do not keep with very small fish or fry, nor with aggressive or overly-territorial fish. May eat snails and pose a risk to other inverts.


Will accept most foods including pellets and flake as well as live/frozen food such as bloodworm, tubifex and daphnia.

Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

Requires a laterally spacious well-filtered tank with good water quality. Does well in planted tanks.


A peaceful schooling fish that occupies the mid-top section of the tank.


This fish has the distinctive Rainbowfish shape and typical bi-colour on the body. The front half of the body varies from yellow-gold to pale green-blue in colour, while the back half varies from red through pink to orange in colour.
