his
species, is the smaller of three from the same African
genus of Anaspidoglanis Teugels, Risch, De
Vos & Thys, 1991. The other two being Anaspidoglanis
akiri (Risch 1987) and Anaspidoglanis boutchangai
(Thys van den Audenaerde 1965). This species has now
been put into a new genus, Notoglanidium,
from the former Anaspidoglanis. The
genera of the Auchenoglanididae were originally assigned
to the spiny catfish (Bagridae, or to the subfamily
Auchenoglaninae), later they were assigned to the
Claroteidae as the subfamily Auchenoglanidinae. In
the fourth edition of Fishes of the World, a standard
work on fish systematics, they form an independent
family. Common features of the family are the rounded
to emarginate caudal fin and the position of the posterior
nostrils on the sides of the upper lip. It contains
the three genera Auchenoglanis, Parauchenoglanis
and Notoglanidium.
Notoglanidium
macrostoma
When aquarists,
through the years, owned this species in their tanks
it was always mooted as, Parauchenoglanis guttatus,
but we now know that Parauchenoglanismacrostoma
was probably the species as P. guttatus was
very rarely imported and so our Factsheet of the Month
started life as Auchenoglanis macrostoma
and then Parauchenoglanismacrostoma
and now to its present day name of Notoglanidiummacrostoma,
and of course on into a new family.
Notoglanidium
macrostoma
Of course needless
to say it needs a large tank to accommodate it and
its larger tankmates and kept singularly. There is
conflicting literature that states that they will
do well in a group but the general consensus is that
this is a loner that is best kept on its own. It is
also a burrower in the substrate so plants may take
a bit of abuse from its activities but all in all
an interesting catfish for the larger community setup.

Characteristics
D 1/7;
A 12, 9 branched. Body elongate, compressed of fairly
uniform depth. Caudal fin truncated. 3 pairs of long
barbels.
Colouration
Upperside brownish, flanks
yellow-brown, underside yellowish. 5 transverse
stripes composed of large, dark blotches which may
more or less run together. A few rows of prominent
spots between the bolder rows of blotches. Fins

Aquarium
Care & Compatibility
This African bagrid is a night
time predator so tank mates would need to be at least
over 3 ins (7cm) to escape its clutches. Tank mates
could include the larger African Characins such as
the Congo Tetras ( Phenacogrammus interruptus)
and the larger American Characins such as from the
Distichodus genera. Larger Barbs like the
Tinfoil Barb (Barbus schwanefeldi) could
be a good choice. Alternately, you could house one
in a Cichlid Community as long as it is not a Rift
Valley set-up as the higher p.H. may prove a bit too
high over a long period of time. Try to keep less
bottom dwellers with a Dwarf Giraffe Catfish as they
are quite territorial and need their own hiding niche
such as a rock/slate shelter so it can rest up during
the day.
Reproduction
Not in the aquarium but in
their native habitat they have been reported that they
build a nest and practice parental care.
Diet
Will feed on almost anything
including worm foods, frozen bloodworm, tablet and
pellet food.
Etymology
Notoglanidium:
otos, back, presumably referring to “rather
long” dorsal fin of N. walkeri; glanidium,
diminutive of glanis, sheatfish (Silurus glanis),
now used as a general term for catfish.
macrostoma:From the Greek makros, meaning
long and stoma, meaning mouth; in reference to the
size of the mouth.
