This is the largest family of catfishes in Asia
with around 100 species known.
is an adipose fin present (confluent with caudal
in some genera and consisting of a small spine
in the elongate Sisor); dorsal fin
base short, fin with or without a spine, adhesive
apparatus in thoracic region present or absent;
four pairs of barbels (however, the monotypic
Sisor has one maxillary pair and five
pairs on the lower jaw). They are not too well
known to aquarists as they are only sporadically
exported. The most common being the genus, Gagata,
Bagarius and Glyptothorax.
Known collectively as "hill stream catfishes"
due to many of them being found in fast flowing
rivers. The Sisorids vary in body shape and
are probably the hardest family for the aquarist
