we bring to you a member of the
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 with the
same size or larger fish but would do better with its own kind
in a large aquarium.
Schilbe 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
Similar looking to Schilbe
marmoratus but this species is smaller with a more light
brown colour pattern and has a marbled appearance but also possesses
the same dark humeral patch as our factsheet of the month.
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.
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
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
(noble). It probably announces the superiority of this species
for its taste.
