last monthly factsheet of the year (2016) brings
us to one of the least kept catfish families,
contains most of the parasitic catfishes and although
the vast majority are small they can be nasty but
none the less they are very interesting in their own
maculatus in its natural habitat enters the gill
chambers of large
catfish such as Luciopimelodus
feeds on the gills. There is a patch of about seven
thorn-like opercular spines and another patch of approximately
nine interopercular spines. These are erectile, and
by first erecting these on one side and then those
on the opposite side, the fish is able to inch its
way forward into narrow openings.
The sub-family Stegophilinae
have sucking mouths with which they can hang on to
the bodies of other fishes.
Distrbution: Lower Paraná and Uruguay River basins,
Argentina. Type Locality:
La Plata, Prov. of Buenos Aires, Argentina.
DoNascimiento, C. (2015) has placed Parastegophilus
in the synonymy of Pseudostegophilus.
Lower Paraná and Uruguay River basins, Argentina.
Type locality: La Plata, Prov. of
Buenos Aires, Argentina.
depressed, body loach-like. Dorsal fin placed posteriorly.
Anal fin behind dorsal fin, ventral fin slightly in
advance of dorsal fin. None of the fin rays are modified
into spines. Maxillary barbels small, minute labial
barble present under maxillary barbel. Copious covering
of mucus over entire body.
Body olive on upper half, lighter
below. A series of black spots along middle of sides,
plus a number of smaller spots above. Large black
blotch at base of caudal fin. Upper and lower lobes
of caudal fin black. Base of dorsal fin dark, remainder
of fin olive.
Care & Compatibility
for the home aquaria with other fish but if kept would
do better on its own with its own kind.
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.
Pseudostegophilus:From the Greek pseudes, meaning
false, stego, meaning cover and philein, meaning to
like; in reference to the resemblance to Stegophilus
("lover of cover", in reference to the secretive
nature), another trichomycterid genus. maculatus: Spotted.
