 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Synodontis macrops Greenwood, 1963 |
| Common Name(s) | None |
| Type Locality | A trib. stream of Aswa R., Teso dist., Uganda. |
| Pronunciation | sin oh don tiss - mah crops |
| Etymology | Synodontis: From the Greek syn, meaning together, and odontos, meaning tooth; in reference to the closely-spaced lower jaw teeth. macrops = large eyes |
| Species Information | |
| Size | 200mm (7.9") 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. Most easily distinguished by its distinct yellow colour. Spotted pattern especially marked in juveniles, but tends to fade with age. |
| 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 | Upper Nile. Distribution largely overlaps that of S. schall. African Waters  , Nile, Upper Nile (hover or click on these areas to show maps or find other species found there) |
| pH | 6.5 - 8.5 |
| Temperature | 20.0-26.0°C or 68-78.8°F (Show others within this range) |
| Other Parameters | pH is best kept at a slightly alkaline level around 7.5, with kH and GH of above 3-4. At lower levels, fin membranes start to deteriorate. Fish seems to do fine at pH and hardness typical of Lake Malawi conditions. |
| Husbandry Information | |
| Feeding | A hungry, fast growing fish that will eat practically anything but is more carnivorous than most Synodontis species. |
| Furniture | Caves, driftwood, plants like Vallisneria. |
| Compatibility | Similar to S. schall. Like S. schall, S. macrops grows quite large and can be an aggressive, boisterous fish. Small fish up to 2 cm may be at risk. Keep with other similarly sized fish. Can be kept in a Rift Lake cichlid tank. |
| Breeding | Unreported. |
