Previously known as O.
leiacanthus but newly described by Tan &
Ng (1996). Description: Anal soft
rays: 53 - 60. Habitat: Inhabits
stenotopic to peats. Collected from shallow blackwaters
in a peat swamp heavily disturbed by logging activities.
Diet: Feed mainly on insect larvae,
with adults eating fish instead. Remarks:
The habitat of this species (blackwater peat swamp
forests) has undergone large scale destruction and
degradation, and a population decline of about 25%
due to habitat degradation and loss is suspected within
the next ten years. Therefore, Ompok fumidus
is assessed as Near Threatened, nearly meeting criterion
A3c (IUCN 2020).

Perak and Pahang (Peninsular Malaysia); Pulau Bintan
(Riau Archipelago), as well as Kalimantan Barat and
