Size 130mm or 5.1" SL. Find near, nearer or same sized spp.
Identification An inconspicuously coloured small catfish which, with its compact body shape, reminds one mostly of 'classic' Peckoltia, from which it is nevertheless differs by its almost straight head profile. Further differences from 'classic' Peckoltia are a very large gap between the eyes, which is around one fifth of the body length (in Peckoltia less than one sixth) and a very domed and furrowed head area. Because of these differences it was briefly classified in a new genus (Sophinancistrus), however now resides back in Peckoltia.
Sexing Unlike other Peckoltia the males of this species don't grow permanent body odontodes. They do grow short odontodes on their caudal peduncles. It seems, however, that they only do this when they are well conditioned and it is their spawning period. The rest of the time, they are unadorned. Females have a wider girth across the body most evident when the area just behind the pectoral fins is viewed from above on well conditioned individuals.

Jump to next section Husbandry Information
Feeding Omnivorous with a tendency towards meaty foods. Not an effective algae eater. Well fed individuals will not damage most plants.
Furniture Rock piles and wood tangles. Plants are not vital.
From Armbruster's Peckoltia revision: The specimens I have collected appear to have been chased from the middle depths of submerged grasses and twigs as the seine was not fully on the bottom. This suggests that the hypertrophied pelvic muscles and widened pelvic-fin spines may be used to grasp the grasses and twigs.
Compatibility Peaceful if a little territorial. As a rough guide give each fish a 12 inch square area well broken up with decorations.
Breeding Cave spawner.
Breeding Reports There is no breeding report.
