长鳍梭大口鱼

Overview

Poorly known Luciosoma spilopleura appears smaller than the commonly traded congeners. Its name has long been misapplied, so a label alone cannot establish that a juvenile will remain comparatively small.

Distribution & habitat

Known localities are confined to Sumatra and Indonesian Borneo. Smaller fast headwater streams over stone and gravel are favored, although juveniles have also been collected near floating structures and flooded bank vegetation in the Kapuas main channel.

Notes

Dense snout and lower-jaw tubercles, vertically elongated flank spots and multiple dark tail bands contribute to identification. The leading pelvic ray lacks the long filament seen in some relatives. Verified aquarium trade in this species has not been established.
