Habitat: Occurs
in rivers and streams. Found in the basin wide tributary
of the lower Mekong. Aquarium Care:
Can be kept in a community tank but would watch if
housing an adult with smaller Characins or Livebearers
as they could be picked of at night when it starts
cruising the tank. They can also nip the fins of larger
species, so keep well fed with a feeding after lights
out to curb this aggression. Diet:
Feeds on aquatic insect larvae, including odonatans.
Reproduction: Adult females captured
in February had well-developed ova. Spawning takes
place at the beginning of the rainy season, with the
young appearing in fishing nets during August. Not
reported in the aquarium but would appear to be a
substrate spawner laying its eggs in tangled roots
in the wild, I guess the p.H.would need to be on the
acid side for any success with this species. There
is a fleshy appendage in front of the anal fin that
would indicate sexual dimorphism which has been noticed
in other Bagrids. Etymology: The
genus name Pseudomystus:

used by Belon in 1553 to describe all fishes with
whiskers. The species name siamensis: from
Siam. (Thailand).
