Classification:
Order:
Siluriformes
Family: Loricariidae

Distribution:
Reports are inconsistent. Some state it to be endemic to the middle and lower rio Negro, Amazonas state, Brazil while others claim it can also be found in Guyana or has a wider distribution within the Amazon basin. The former appears most likely and a large degree of this confusion can be attributed to it being misidentified for several decades (see ‘Notes’). Type locality is given simply as ‘Manaus, Brazil’.

Habitat:
Inhabits flowing streams and tributaries containing acidic black water.

Maximum Standard Length:
180 – 200mm.

Aquarium Size:
An aquarium with base dimensions of 120 x 45cm or equivalent should be the smallest considered.

Maintenance:
Not difficult to maintain under the correct conditions, we strongly recommend keeping it in a tank designed to simulate a jungle stream with a substrate of sand and tangles of driftwood roots and branches. Lighting can be quite dim unless you intend to grow plants, which should ideally be of species able to grow attached to items of decor, while a few handfuls of dried leaf litter would complete the natural effect and provide additional cover. Like many fishes that hail from pristine natural habitats it’s intolerant to accumulation of organic wastes and requires spotless water in order to thrive. For this reason it should never be introduced to biologically immature set-ups and adapts most easily to stable, mature aquaria.

Water Conditions:
Temperature:
26 – 30°C
pH: 5.0 – 7.0
Hardness: 18 – 179ppm

Diet:
Wild specimens are probably omnivorous foragers but with a preference for aquatic invertebrates and suchlike. In the aquarium it does best when offered a varied diet comprising sinking dried foods, frozen Daphnia, mosquito larvae, chironomid larvae (bloodworm), and prawn/shrimp, for, example, plus some fresh fruit, parboiled potato, etc. Home-made foods using a mixture of natural ingredients bound with gelatin are very useful since they can be tailored to contain fresh vegetables, Spirulina and meatier ingredients.

Behaviour and Compatibility:
Relatively peaceful but territorial with conspecifics and similarly-shaped species.

Sexual Dimorphism:
Adult males possess well-developed odontodes on the pectoral fins and opercle and tentacles on the head while females do not.

Reproduction:
Cave-spawner with the male responsible for brood care.

Notes:
This species is not always identified correctly with its name used for the unidentified common bristlenose and other similar species, while the fish itself has been referred to as A. hoplogenys and assigned the L-number L183.
