Relevant Information:

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.
