 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Liosomadoras oncinus (Jardine & Schomburgk in Schomburgk, 1841) |
| Common Name(s) | Jaguar Catfish |
| Type Locality | Padauiri River |
| Synonym(s) | Arius oncinus |
| Pronunciation | lie oh SEW ma DOOR uss - ONN sin uuss |
| Etymology | From the Greek leios, meaning smooth, soma, meaning body and Doras (a genus of doradid catfishes); in reference to the lack of bony plates on the body (when the genus was described as a doradid). Oncinus from the Latin name of this species namesake, the Jaguar (Panthera onca) |
| Species Information | |
| Size | 250mm (9.8") SL. Find near, nearer or same sized spp. |
| Identification | A beautiful, Jaguar-style, patterned fish that is unmistakable. This species is widely distributed but doesn't appear to show any great difference in appearance between species from different origins. |
| Sexing | Sexually mature males have a genital papilla which is a modification of the anal fin, they also have thicker and more robust dorsal and pectoral fin spines. Harder to sex younger individuals. |
| General Remarks | A species that becomes active at late dusk and remains so until first light. Spends all of the daytime crammed into a dark spot in the aquarium, or, in nature, driftwood crevices and holes. Liosomadoras is the only genus in Auchenipteridae with a postcleithral process, which is the reason this genus was previously placed in Doradidae. |
| Habitat Information | |
| Distribution | South America: Ucayali, Amazonas and Negro river basins. Amazon, Middle Amazon (Solimoes)  , Negro (hover or click on these areas to show maps or find other species found there)Amazon (hover or click on these areas to show maps or find other species found there) Amazon, Upper Amazon, Marañón , Ucayali (hover or click on these areas to show maps or find other species found there) |
| pH | 5.6 - 7.2 |
| Temperature | 20.0-28.0°C or 68-82.4°F (Show others within this range) |
| Other Parameters | Care is required with this species upon import as it is not often clear what water parameters (in the wild) it is used to. It's a reasonably hardy fish, so best to acclimatize in pH of around 6.4-6.6 if the origin is unknown. |
| Husbandry Information | |
| Feeding | Accepts a wide variety of foods. Larger frozen foods are preferred. Should be fed when the tank is dark or dimly lit. |
| Furniture | Provide many hiding spots as this fish is very shy and nocturnal if kept in well lit aquaria. Lots of wood, floating plants and dim lighting will allow the fish to feel more comfortable. |
| Compatibility | In general a peaceful fish. It will however fiercely defend its hiding spot against intruders. |
| Suggested Tankmates | Other peaceful fish that are too large to swallow. Enjoys the company of its own species. |
| Breeding | Unreported |
