Centromochlus Macracanthus

Datasheet

General Description

Centromochlus Macracanthus, commonly known as the Wood Catfish, is a species that belongs to the Auchenipteridae family within the order Siluriformes. These catfish are often found foraging at night among submerged woody structures in their natural habitat. They are relatively small in size, reaching a maximum of 7.1cm.

Aquarium Setup

When setting up an aquarium for Centromochlus Macracanthus, it is recommended to replicate a flowing stream environment. This can be achieved by incorporating a substrate of variably-sized rocks, sand, fine gravel, and water-worn boulders. Additionally, adding driftwood branches, terracotta pipes, and plant pots to create hiding spots and shaded areas mimics their natural habitat. These catfish also appreciate sheltering among surface vegetation like Ceratopteris spp. (see table for specific water conditions).

Behaviour

During the day, Centromochlus Macracanthus tends to seek refuge among submerged woody structures but becomes active at night when foraging for food. Unlike many other catfish species, they are known to actively feed at the surface and readily leave their hiding places at feeding times.

Feeding and Diet

Wood Catfish are known to have a varied diet in captivity, accepting sinking dried foods but showing a preference for small live and frozen varieties such as bloodworms and Tubifex. Once acclimated, they eagerly emerge to feed when food is introduced and exhibit surface feeding behavior.

Reproduction & Dimorphism

Within the Auchenipteridae family, Centromochlus Macracanthus is believed to practice internal insemination. Females can carry mature, unfertilized eggs and sperm packets within their bodies until conditions are suitable for fertilization. There is no significant parental care following egg deposition.

Habitat and Distribution

The type locality for Centromochlus Macracanthus is São Pedro, Rio Negro, Amazonas, Brazil, with the species endemic to the upper Rio Negro system. They are typically found in South American waters, taking refuge among submerged woody structures during the day in their natural habitat, hence the common names such as 'wood' or 'driftwood' catfishes.
