Cat-eLog Data Sheet
Scientific Name	**Synodontis schoutedeni** David, 1936
Common Name(s)	Yellow Marbled Syno
Type Locality	Kungungu, Zaire.
Pronunciation	sin oh don tiss - shouted en aye
Etymology	Synodontis: From the Greek syn, meaning together, and odontos, meaning tooth; in reference to the closely-spaced lower jaw teeth.
Species Information
Size	127mm (5") 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. An attractively marked fish with a very variable vermiculated pattern. Similar markings can be found on several other species within the Genus. If anything the pattern becomes smaller but more intense with age. Well conditioned fish will often develop a bold yellow base colouration which is quite striking.
Sexing	First lay the fish in your hand with its head toward your palm and the tail toward your fingers. Hold the dorsal spine between your middle and ring finger so the fish is belly up and you won't get stuck (Which by the way, hurts like crazy!). The genital pore is in a small furrow of tissue (in healthy fish) and will be obstructed by the pelvic fins. Pull down on the tail gently to arch the fishes spine and the pelvic fins will stand and the furrow open to display the genital pore and the anus of the fish. The male has a somewhat ridged genital papillae on which the spermatoduct is on the back side, facing the tail fin. A gravid female will also show an extended papillae but the oviduct is on the ventral side of the papillae (And may also show a little redness if really gravid). A thin or emaciated female will have just two pink pores, the oviduct and the anus.
Habitat Information
Distribution	Central Congo Basin African Waters , Congo, Middle Congo (hover or click on these areas to show maps or find other species found there)
pH	6.0 - 7.6
Temperature	22.0-26.0°C or 71.6-78.8°F (Show others within this range)
Other Parameters	Many specimens of S. schoutedeni have a tendency to bloat. The cause of this is not yet precisely known.
Husbandry Information
Feeding	Omnivorous. This fish is not a fussy eater.
Furniture	A big pile of rocks with plenty of spaces between the rocks or a jumble of pipes are best. These should be arranged so that the fish can rest upside down or vertically but rarely the ''normal'' way up.
Compatibility	Territorial but, as Synodontis go, unaggressive.
Suggested Tankmates	Larger barbs, rainbowfish perhaps and medium sized cichlids.
Breeding	See Shane's World article.
