| Common Name(s) | None |
| Type Locality | Brazil |
| Synonym(s) | Auchenipterus trachycorystes, Trachycorystes typus |
| Etymology | Trachycorystes: From the Greek trachys, meaning rough and korystes, meaning one armed with a helmet; in reference to the rugose cranial shield. |
| Species Information | |
| Size | 450mm (17.7") SL. Find near, nearer or same sized spp. |
| Identification | This Auchenipterid looks slender. It is the same colour all over (usually black) including the belly. Some report their fish having a brown colour, perhaps this is a different species. Even more striking is the protruding lower jaw that gives this species idenity easily away. |
| Sexing | Males have a genital papilla and do not grow as large as females. Males are also reported to develop thickened barbels and/or larger dorsal spines. |
| General Remarks | Of the handful of Trachycorystes that are known to science,Trachycorystes trachycorystes is the only one that is known to be exported and even that is on a very irregular basis. |
| Habitat Information | |
| Distribution | South America: Amazon basin. Amazon (hover or click on these areas to show maps or find other species found there) |
| pH | 6.4 - 7.0 |
| Temperature | 23.0-29.0°C or 73.4-84.2°F (Show others within this range) |
| Other Parameters | Generally undemanding. |
| Husbandry Information | |
| Feeding | Everything that fits its (huge) mouth. Preferably live food and plenty of it. Larger frozen foods will also be eaten. No daphnia and such! Happily eats prepared foods too. |
| Furniture | Large pieces of driftwood as hiding places. Yet these fish also need swimming space for their nocturnal escapades. Make sure tank covers are secured for this species may jump in the beginning. |
| Compatibility | An aggressive fish that requires a species tank with plenty of refuges, as this species will also attack its own congeners when it feels like it (see Reference; TFH article by K & B Teats). Don't put smaller fish in the same tank, not even fish that may be able to defend themselves well: in the end, they will be killed. |
| Suggested Tankmates | Only very large fish; certainly no easily scared species like (full grown) angelfish and such. |
| Breeding | Unreported. |
