Habitat:
Found mainly in ponds, ditches, swamps and marshes,
but sometimes occurs in muddy rivers. Can tolerate
slightly brackish water. Reproduction:
Breeds in confined waters during the monsoon months,
but can breed in ponds, derelict ponds and ditches
when sufficient rain-water accumulates. Oviparous,
distinct pairing possibly like other members of the
same family. Aquarium Care: Apart
from giving it the utmost respect when handling, it
does very well in a larger aquarium, and you can either
keep it alone with other inhabitants that are too
big for its mouth (large Barbs, Cichlids etc.) or
in a group situation if you would like the challenge
of breeding them. A sand substrate is best with hiding
places of rock and cave work and making sure that
it has plenty of swimming space, as they do like to
cruise the tank during the night time hours. Keep
your regular water changes up with good filtration
as they are a greedy species, and can make a mess
of your aquarium if good husbandry is not adhered
to. Diet: Omnivorous. Etymology:
The specific name fossilis: Latin for digging
or dug up, allusion not explained; according to Shaw
(General Zoology, vol. 5, 1804), it is “sometimes
dug out of the mud at the bottom, in the manner of
[the cobitid loach] Cobitis fossilis”. Update2021: The
genus Heteropneustes has now been
removed from the Clariidae family
and reinstated to the Heteropneustidae
Hora, 1936 and
H. microps has been deemed to be a synonym
of H. fossillis.

IUCN
Red List
Heteropneustes
fossilis has a very wide range (Pakistan, India,
Sri Lanka, Nepal, Bangladesh, Myanmar, Thailand and
Laos) and has been introduced elsewhere. Whilst it is
heavily utilised for food and for medicine in many parts
of its range, and it may be threatened by over-exploitation
and habitat loss and degradation (especially from pollution
and dams), it is not thought that any global population
decline is likely to meet (or be close to meeting) the
threshold for Vulnerable. Therefore the species is assessed
as Least Concern, (IUCN 2019).
