Size 350mm or 13.8" 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 identity 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.

Down arrow 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 avoid slow moving species like (full grown) angelfish and fishes that would compete for refuge with this brute.
Breeding Unreported.
Breeding Reports There is no breeding report.
