Origin[edit | edit source]

South America: Orinoco and Amazon River basins; and coastal rivers in the Guianas.


Sexing[edit | edit source]

Mature males are larger and more colourful than females with a more dramatic dorsal fin.


Tank compatibility[edit | edit source]

A shy fish, this Characin does not shoal and males can be quite territorial to one another. Best kept as a single male with a group of females. Cannot be kept with larger aggressive or predatory fish. Keep with a shoal of dither fish to make this fish feel more secure.


Diet[edit | edit source]

Will generally not accept dry food, feed with live/frozen food such as bloodworm, daphnia and brine shrimp.


Feeding regime[edit | edit source]

Feed once or twice a day.


Environment specifics[edit | edit source]

Must be kept in acidic water, peat filtered is best. A dimly lit tank with dense planting and floating plants and a dark substrate will make this fish feel secure.


Behaviour[edit | edit source]

A shy, mostly mid-bottom dwelling, fish. Males will be territorial to other males of the same species.


Identification[edit | edit source]

An elongate fish with a slightly humped back. The body is silver-yellow in colour and iridescent with a defined lateral line. It has a forked caudal and elongated dorsal and anal fins, the dorsal has a trailing filament, more prominent on males. The fins are iridescent, translucent with slight spotting.
