Rhinodoras Dorbygnyi

Datasheet

General Description

The Rhinodoras Dorbygnyi, also known as the talking catfish, is a species with limited information available in the hobby. Reaching a maximum size of 50.0cm, it is a shy and nocturnal fish that can be a unique addition to larger community tanks.

Aquarium Setup

For this species, a dimly-lit tank is recommended due to its nocturnal nature. Providing ample hiding spots like clay flowerpots, plastic piping, and driftwood is essential. While plants are not mandatory, they can help reduce direct light exposure and offer additional shelter. Consider using a red light to observe the talking catfish foraging at night; they tend to become more active and visible as they mature.

Behaviour

The talking catfish is entirely non-aggressive, but it may consume smaller fish, making it unsuitable for general community setups. It can coexist with larger, peaceful species like characins, cichlids, and non-territorial catfish. Tolerant of its kind, this species often groups together and shares shelters during the day. While minor hierarchical scuffles might occur, they rarely result in physical harm.

Feeding and Diet

As an omnivorous species, the talking catfish is easy to feed. A diet primarily composed of sinking pellets or tablets supplemented with live or frozen foods like bloodworms and earthworms is ideal. Initially, they may feed only after dark, requiring food to be provided accordingly. Once acclimated, many individuals will actively forage during feeding times.

Reproduction & Dimorphism

Reproduction details of the talking catfish remain unreported in the aquarium trade, and any sexual dimorphism is yet unknown.

Habitat and Distribution

This species inhabits slow-moving waters, including tributaries, creeks, and swamps, typically seeking shelter among roots or submerged vegetation. Found throughout the extensive Rio Paraná basin, the talking catfish is native to regions spanning Bolivia, Paraguay, Uruguay, Argentina, and Brazil.
