Its said to become attached
to the gills, anal region and fins of dead, dying,
or disabled fishes. Not recommended for the home aquaria.
Diet: Difficult to feed with aquarium made
foods as this is a species that feeds of fish, scales
and body mucus so certainly
a catfish for the specialist. Etymology:
The specific name nemurus: Thread-tailed,
from nëma, thread, and ourá, tail, referring
to filamentous upper lobe of caudal fin.
Remarks:
The sub-family Stegophilinae
have sucking mouths with which they can hang on to
the bodies of other fishes. DoNascimiento, C. (2015):
has placed Parastegophilus in the synonymy
of Pseudostegophilus and you can still sometimes
find the synonym, Parastegophilus nemurus,
on online searches for this species.
