bring to you a member of the Schilbeidae
family and a catfish that may
not look too garish but still, in my opinion, has
a subtle charm all of its own with its shades of grey
and the dark patch on the operculum.Not for a small aquarium
of course as this species can grow upwards to 30cm
(12ins) and as such would need to be housed withthe same size or larger
fish but would do better with its own kind in a large
intermedius feeds on a wide range of invertebrates
including terrestrial insects and whole or pieces
of fish. Primarily piscivorous at 13-34 cm TL
. It rarely grows larger than 30 cm SL . The greatest
predation pressure was exerted on the cyprinid, Barbus
radiatus, which made up 29% of all identifiable
fish species. Spawns throughout the year peaking once
and migrates into rivers in fairly compact schools
during the rainy season to spawn in floodwater pools.
Keep with a group
of four or more in a large size aquarium from 150cm
(5ft.) upwards that is well-filtered having a pH ranging
between 6.5 and 7.2 and a temperature of between 23
and 26°C. Provide wide open spaces, long grass
like plants with a few pieces of bogwood positioned
around its margins and that would make an ideal habitat
for a small group of Schilbe intermedius.

River basins. Africa: Nile River in Sudan. Reported
from the Okavango Delta, Botswana, Zambia, Mozambique
and South Africa. Type locality:
Dorsal spines (total): 1 -
1; Dorsal soft rays (total): 5 - 6. Anal fin long,
extending from vent almost to origin of caudal fin.
Four pairs of short, circum-oral barbels.
Ground colour silverish, brownish
to olive on the back and upper parts of the head.
There are two dark grey to olive bands, the longest
running in the middle of the flanks along the lateral
line from the upper gill cover to the caudal peduncle.
At the beginning of this band there is a dark humeral
spot. The second band is shorter, running from the
beginning of the pectorals only to the end of the
anal. Fins transparent, the anal with a dark band
near the body; a dark streak runs into each lobe of
the deeply forked caudal fin.
Care and Compatibility
Large aquarium with tankmates
not too small as they could become prey during night
time activities. Will do better with conspecifics.
Not achieved in
the aquarium. Oviparous, eggs are unguarded.
S. intermedius is
sexually dimorphic with females growing to a larger
size than males. The modal length of females was 20-21
cm SL. (8-8¼ins) and males 14-15 cm SL. (5½-6ins).
Diet is no problem as they
will eat most aquarium fare.
