Ompok pinnatus • Siluridae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Ompok pinnatus** Ng, H.H., 2003
Common Name(s)	None
Type Locality	Cambodia: Tonle Sap at Kompong Chhnang
Pronunciation	Awm pok - peen ah tuss
Etymology	The etymology of Ompok is unclear. It is believed to be a corruption of the Indonesian name for mid-sized silurid catfishes, limpok. From the Latin pinnatus, meaning feathered or plumed. In reference to the very long dorsal fin and barbels.
Species Information
Size	81mm (3.2") SL. Find near, nearer or same sized spp.
Identification	The catfish genus Ompok La Cepède, 1803, consists of medium-sized silurid fishes found in inland waters throughout South and Southeast Asia. The genus is traditionally diagnosed by the presence of a short dorsal fin with 4 rays, strongly forked caudal fin, subcutaneous eye that is set immediately posterior to the mouth rictus and two patches of palatal teeth (Weber & de Beaufort, 1913). Bornbusch (1995) showed that Ompok, as currently understood, is probably paraphyletic. Like O. eugeneiatus, easily distinguished from congeners by the very long barbels. Ompok pinnatus differs from O. eugeneiatus in having a deeper caudal peduncle, shorter mandibular barbels and fewer anal-fin rays.
Sexing	Males are more slender and have strong serrations on the posterior edge of the pectoral spine (females lack these serrations).

pH	6.0 - 7.0
Temperature	22.0-28.0°C or 71.6-82.4°F (Show others within this range)
Husbandry Information
Feeding	Readily feeds on live or frozen foods and other prepared foods such as pellets. May eat very small fishes.
Furniture	Provide hiding spaces in the form of driftwood or PVC pipes as well as plenty of vegetation. Prefers an area of open water when active.
Compatibility	A relatively peaceful species that is compatible with most fish. Not safe with very small fishes.
Breeding	Unreported.
