Geographic Range [top]

Range Description: This species appears to be relatively common around Iquitos and probably in another localities in the Peruvian Amazon. The species apparently also occurs in Colombia and Brazil, although in the latter the similar-looking Hemigrammus haraldi also occurs and misidentification of collections may have been made (Lima pers. comm. 2007).

Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: H. pulcher is a benthopelagic (ecological region at the lowest level of water body) species. Lives in large streams and rivers, and probably associated flood plains. A generalist mid-water swimmer, feeding on insects, plant matter, and the like.
Systems: Freshwater
Congregatory: Congregatory (and dispersive)

Use and Trade [top]

Use and Trade: The species is harvested for the pet trade, although not currently at a level that is causing concern.

Threats [top]

Major Threat(s): It is harvested for the aquarium trade, but probably not as intensively in a way that could jeopardize natural populations. There are no other meaningful impacts are known to affect the species.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place and research into the population trends are required.
