Synodontis granulosa • Mochokidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Synodontis granulosa** Boulenger, 1900
Common Name(s)	Granny, White Seam Synodontis
Type Locality	N. end of Lake Tanganyika.
Synonym(s)	Synodontis granulosus
Pronunciation	sin oh don tiss - gran you LOW suss
Etymology	Synodontis: From the Greek syn, meaning together, and odontos, meaning tooth; in reference to the closely-spaced lower jaw teeth.
Species Information
Size	250mm (9.8") SL. Find near, nearer or same sized spp.
Identification	All species in the genus Synodontis have a hardened head cap that has attached a process (humeral process) which is situated behind the gill opening and pointed towards the posterior. The dorsal fin and pectoral fins have a hardened first ray which is serrated. Caudal fin is always forked. There is one pair of maxillary barbels, sometimes having membranes and occasionally branched. The two pairs of mandibular barbels are often branched and can have nodes attached. The cone-shaped teeth in the upper jaw are short. S-shaped and movable in the lower jaw. These fish produce audible sounds when disturbed rubbing the base of the pectoral spine against the pectoral girdle. At least 1/3 to 1/2 of all fins have a snow white edging. Long white barbles. Inky sheen to brownish body which bears a spotted pattern in younger fish. The contrast of this spotting diminishes with age.
Sexing	Both sexes have identical colouration. Females grow slightly larger and tend to be plumper than males. Males have a 4-5 mm genital papilla near the anus.
Habitat Information
Distribution	Lake Tanganyika, East Africa African Waters, Western Rift Valley Lakes, Tanganyika (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
pH	7.8 - 8.4
Temperature	24.0-28.0°C or 75.2-82.4°F (Show others within this range)
Husbandry Information
Feeding	Voracious eater that will accept virtually all aquarium food, but prefers meaty foods such as shrimp and clam. Apparently feeds on small molluscs in the wild.
Furniture	A network of caves formed by piling up rocks, with ample swimming space above. Vallisneria and / or hornwort is optional.
Compatibility	Best kept in a tank of 125 gallons (500 liters) or more. May become reclusive and aggressive in tanks smaller than 70 gallons (250 liters). May jump out of tank in first few days after initial introduction.
Suggested Tankmates	Tanganyikan Synodontis, robust Tanganyikan cichlids and Tanganyika eels.
Breeding	Breeding has been reported by a UK based wholesaler, but no details have been made available. Has also been bred by hormone injection in Eastern Europe.
