Hengel’s rasbora

Trigonostigma hengeli

Orange edging on a silvery body

A pale grey-silver body has a bright orange edge above and in front of its black hatchet marking.

Native range: The Tambesi and Batang Hari drainages in Jambi, Sumatra, Indonesia.

Natural habitat: Inhabits slow forest streams and tributaries with dense submerged plants, fallen leaves and wood, sometimes in lightly brown water.

Provide conspecific company, planted cover and swimming room. Subdued light helps reveal the orange border.

Appearance and identification

T. espei has more extensive copper-orange body colour, while T. heteromorpha is deeper with a broader wedge.

Keep at least 8–10 conspecifics.

Allow a 60 × 30 cm base.

Offer suitably small prepared foods with small frozen and live foods.

Check predation, feeding competition, space and water.

Planting and floating shade provide cover; retain a group swimming lane.
