maculatus (Steindachner, 1879)
he last monthly factsheet of the year (2016) brings
us to one of the least kept catfish families,
Trichomycteridae, which 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 right.
maculatus in its natural habitat enters the gill chambers
catfish such as Luciopimelodus
pati and 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.
Head 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.
Not recommended 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.
