|IUCN Red List Category||Data Deficient, range map and more is available on the IUCN species page. Last assessed 2011.|
|Other Parameters||H. leptorhynchus in the Mekong stays in permanent river channels and does not move into the flooded forest. This species migrates upstream when water levels begin to rise at the beginning of the flood season and moves downstream as the water clears at the end of the flood season.|
|Feeding||Gut contents of wild-caught specimens include primarily gastropod and bivalve mollusks. Food selection varies with age and size: Younger, smaller fish eat gastropods; as fish grow, food choice expands to include bivalves (Grudpan et al., 2016).|
