his month (March 2004)
we arrive back to the Mochokidae family and a Synodontis
that is not too well known or written about but never-the-less,
a fine addition to the medium to large sized community
tank.
Synodontis
greshoffi was collected by its namesake, M.A.
Greshoff, in the area around Kinshasa, Stanley Pool,
in the upper Congo River. near Brazzaville, Zaire
(now the Democratic Republic of the Congo) and the
new species was so named by the above author, L. Schilthuis,
in a paper written by him in 1891.
Synodontis
greshoffi
As
stated this is a fairly easy and tolerable species
to keep, and a good looker to boot. It can be housed
alongside other non aggressive species of Synodontis
as long as they are given plenty of shelter such as
pipes, rockwork etc to subdue any territorial tendencies
between each species. I think with most Synodontis
you have to watch them, and who you put in to their
quarters with them, as some can be more aggressive
than others. Synodontis can be territorial,
so give them cave structures to make them feel more
secure in their surroundings.
The
following image shows the serrations on the interior
and exterior of the pectoral spines and also the reticulated
pattern on the belly.
Synodontis
greshoffi-
ventral view
There has been a reported import of an albino version
into the U.K. in 1988 and an article on this species
and others on the subject of fish albinism written
in the monthly aquatic magazine, Practical Fishkeeping,
by David Sands in that year. This may have been this
species or Synodontis
schoutedeni
as the body patterns are somewhat similar.
Distrbution: The
map here shows the area around Kinshasa and
Malebo (Stanley) Pool.
The genus Synodontis
sports three pairs of barbels 1pair: maxillary, 1
pair: outer mandibular and one pair of inner mandibular
barbels that are branched (filaments). There are only
three species that have filaments on their maxillary
barbels as well as the mandibular, and they are, S.
clarias, S.
decorus and S.
flavitaeniatiatus.
Africa: Congo
River basin, except Luapula River system and lower
Congo. Type locality: Kinshasa, Stanley
Pool.
Size
20.0cm (8ins)
Temp.
23-27°C
(73-81°F)
p.H.
6.5-7.2.
Characteristics
Percentage of the length: height
of the body 27 (19, 7 to 30, 9), length of the head
29,9 (26,8 to 32,9), maxillary barbels 50,2 (39,3
to 64,4) distance of the muzzle to the origin of the
dorsal 42,8 (37 to 43,1) base of the adipose 31,9
(22,7 to 31,9) dorsal spine length 33,8 (20,5 to 33,8)
length of the pectoral thorn 34,8 (25 to 34,8) Serrated
exterior and interior of pectoral spine.
Colouration
Depending on aquarium conditions,
pH and colour of substrate. Cream base body colour
with brown to golden reticulated markings to body
which continues on to belly area. Pattern becomes
more intense on the head. Brown spots on all fins.
Aquarium
Care and Compatibility
Nice temperment and will do
well in the larger community tank alongside larger
barbs and characins such as the Congo tetra.
Reproduction
Not recorded.
Diet
Can be fed a varied diet of
good quality flake, tablet food, pellets, worm foods
and frozen food such as bloodworm.
Etymology
Synodontis:
Ancient name for an undetermined fish from the Nile
(Cuvier 1816). greshoffi: Named after its
collector, M.A. Greshoff.
