 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Ageneiosus magoi Castillo & Brull G., 1989 |
| Common Name(s) | Slopehead Catfish |
| Type Locality | Orinoco basin |
| Pronunciation | ah genie OH sus - mah go eye |
| Etymology | Ageneiosus: From the Greek a, meaning without and genias, meaning beard; in reference to the apparent lack of barbels (the fish has very short maxillary barbels that are almost indistinguishable). |
| Species Information | |
| Size | 240mm (9.4") SL. Find near, nearer or same sized spp. |
| Identification | Easily recognized by the black and white pattern, although the pattern itself can differ a lot. |
| Sexing | Like all Auchenipterids, males have a genital papilla. Moreover, sexually active males get an enlarged and slightly curved dorsal spine and thickened barbels, that are used to clasp the female. After the breeding season, the dorsal spine and the barbels grow back to their normal sizes. |
| General Remarks | Wild caught specimen show some yellow on their body and fins, which disappears after some time in an aquarium. In contradiction to most other Auchenipterids, this species may be very active during the day. |
| Habitat Information | |
| Distribution | Orinoco basin. Orinoco  (hover or click on these areas to show maps or find other species found there) |
| pH | 6.4 - 7.0 |
| Temperature | 23.0-30.0°C or 73.4-86°F (Show others within this range) |
| Husbandry Information | |
| Feeding | Voracious feeder that will eat anything that fits its mouth. Live fish, large frozen foods and pellets. When feeding live fish choose a proper source. It's best to breed them oneself. Feeding just goldfish is not recommended, as the quality of captive bred goldfish can be poor - which may cause diseases - and it's a very one sided diet. |
| Furniture | Some pieces of driftwood as hiding spots. This species loves to swim against the current, so a large pump is obligatory. Provide lots of swimming space. |
| Compatibility | Will ignore fish that it can't swallow. |
| Suggested Tankmates | Larger catfishes like other Auchenipteridae, Doradidae and Loricariidae. Non-aggressive Characins like Metynnis. |
| Breeding | Unreported. |
