  • Scientific name: Auchenipterichthys coracoideus
  • Synonyms: Trachycorystes coracoideus
  • Common name: Zamora Woodcat, Midnight Catfish
  • Group: Catfishes
  • Habitat: South America; Brazil, Peru; widely-distributed in the upper and central parts of the Amazon basin.
  • Size: 9-11 cm
  • Biotope: Found in turbid rivers, tributaries and flooded areas, usually around the submerged roots during daytime. At night they often feeding in open water.
  • Social behavior: A peaceful and shy catfish, but may hunt down very small fish. It can be kept with other peaceful characins, cichlids and catfishes. This species can be maintained singly or in a small group.
  • Diet: Omnivorous; mainly feeds on insects and their larvae in nature, but can be fed with live, frozen and often with dried foods in aquarium. Nocturnal, so it should be fed after the lights out.
  • Breeding: It is rare in aquarium.
  • Tank: Minimum 90 litres
  • Population: 3 fishes for 130 litres
  • Decoration: Provide lots of hiding places, or dense vegetation, and keep water movement to a minimum. The fish will be seen much more often under subdued light.
  • Temperature: 22-25 °C
  • pH: 6-7.2
  • Hardness: 0-10 NK°
  • Lifespan: 5-8 years

Description: Zamora Woodcat has a beautiful inky bluish-grey body color, covered with small white spots. The dorsal fin has a black tip, and the pectoral and dorsal fin’s first spines are also black. The common name of Auchenipterichthys coracoideus stems from the catching locality around the Zamora region of Peru where these fish caught in fairly large numbers. Zamora Woodcat has often been misidentified as Auchenipterichthys thoracatus, but since a study in 2005 this species is instead Auchenipterichthys coracoideus. The two catfish are very similar in appearance, but they differ principally in the number of anal fin rays: Auchenipterichthys coracoideus normally having less than 26 anal fin rays (usually 23), and Auchenipterichthys thoractus typically more than 25 (usually 27). In addition Auchenipterichthys thoractus lives restricted in the upper Madeira River basin in southwestern Brazil and eastern Bolivia, while Auchenipterichthys coracoideus is more widely-distributed throughout much of the Amazon region. Also Auchenipterichthys thoracatus males apparently don’t develop an extended dorsal spine as in Auchenipterichthys coracoideus.

Males develop a hook-like extension at the tip of the anal fin which is used during the spawning, and also the dorsal spine becomes greatly elongated. Only a few information is available about their breeding, but it is possible in aquarium. Fertilisation is internal, with the male using his modified anal fin in a similar fashion to the gonopodium possessed by live-bearing toothcarps. The female is depositing the fertilized eggs on the substrate, or among the aquatic vegetation. After spawning no parental care has been observed. Females can store sperm for later use as they have been observed laying fertile eggs in isolation from the male.
