most
sought after species from the Mochokidae family is
the very stunning looking Synodontis granulosus.
This Synodontis is not very abundant
in Lake Tanganyika as it lives in a deep water habitat
with a solitary lifestyle so the price in your LFS
will always be high if you are lucky enough to see
this beautiful species.
Synodontis
granulosus
There are hybrids
around pertaining to be this species but the price
will be the first warning sign as cheaper fish means
there is a good chance that it is not S. granulosus
but a hybrid hormone bred in the Czech Republic, where
they have been very adept at producing hormone bred
injected hybrids for many years for the aquatic trade.
As in the above image you can see the true trait of
Synodontis granulosus with all fins black
with a white margin and (according to the light source)
a blackish/brown body.
Synodontis
granulosus
Above is a specimen
showing a lighter body colour due to the stress or
bright light with small black spots. A large aquarium
of at least 60ins x 24ins x 24ins (150cm x 60cm x
60cm) would be better as they do not do well in small
aquaria.
Distrbution: Africa:
Burundi, Tanganyika. Type
locality:
North end of Lake Tanganyika.
In the IUCN Red
List of Threatened Species it has a tag of Least
Concern. Lives in areas of shells, sand and
mud/silt, over a wide depth range, but more often
between 20–40m. Thought to feed on invertebrates.
Common
Name
Granular Synodontis
Synonyms
None
Family
Mochokidae
Subfamily
Mochocinae
Distribution
Africa:
Burundi, Tanganyika. Type locality:
North end of Lake Tanganyika.
Size
25.0cm (10ins)
Temp.
23-26°C (73-79°F)
p.H.
7.5-8.5.
Characteristics
Deep body with the caudal peduncle
fairly shallow. Humeral process is long and narrow,
keeled below, and pointed at the tip.
High and long adipose fin which
originates just behind the dorsal fin. Caudal
fin is deeply forked.
Colouration
Adults have a grey-brown body
which they are small indistinct dark spots. Fins are
black/brown with white margins to the posterior parts.
Barbels white. Juveniles are lighter with a pattern
pf distinct dots and spots.
Aquarium
Care & Compatibility
Usually better to keep as a
lone specimen as two individuals will fight. Either
that or keep five or six in a large biotope lake aquarium
as this will dilute the aggression. Will be okay with
other species of Synodontis. Keep as with
all members of Synodontis from Lake Tanganyika,
with a higher p.H. value. Would do well in a large
lake biotope aquarium with hard water cichlids but
would pick of any small juveniles at night.
Reproduction
Oviparous. Distinct
pairing during breeding.
Sexual
Differences
The genital papilla on males
is well developed and pointed, while the females have
only a lightly raised, rounded protrusion and also a
stockier looking body.
Diet
Omnivores: Will eat most aquarium
fare, vegetable, meaty and prepared foods.
Glossary
of Terms
Adipose
fin: Fleshy finlike projection without rays,
behind the rayed dorsal fin. Caudal fin: The tail. Caudal peduncle: The narrow part of
a fish's body to which the caudal or tail fin is attached. Dorsal fin: The primary rayed fin(s)
on top of the body. Humeral process:
Bony extension of the pectoral girdle. Hybrid: The progeny of two individuals
belonging to different species; the progeny of two individuals
belonging to different subspecies of the same species
are not hybrids.
Etymology
Synodontis:
Syn = together; odontis = teeth
(fused tooth plates). granulosus: Named after
the nature of skin with granules.
