Rineloricaria Fallax

Datasheet

General Description

The Whiptail Catfish, scientifically known as Rineloricaria Fallax, is a commonly sold catfish species belonging to the Loricariidae family. Typically reaching up to 15.5 cm in size, this species is known for its peaceful nature, making it a suitable addition to a community aquarium setup.

Aquarium Setup

For an optimal aquarium setup for Whiptail Catfish, a biotope environment is recommended. This setup typically includes a layer of sand with scattered dried leaves, branches, rocks, or PVC piping for caves. The tank should not have very bright lighting, and suitable tankmates include small characins, Apistogramma, Corydoras, and other peaceful fish species. The water conditions should ideally have a pH range of 5.8-7.8, hardness of 1-25°dH, and a temperature range of 15-25°C.

Behaviour

Known for its peaceful demeanor, the Whiptail Catfish can dwell harmoniously with various other fish species. It exhibits a non-territorial nature except during spawning. It is best kept in small groups and does not fare well in higher temperatures. When housed with appropriate tank mates, this catfish is not shy and can thrive in community setups.

Feeding and Diet

In its natural habitat, the Whiptail Catfish feeds on aufwuchs and small aquatic crustaceans. In an aquarium setting, it displays an omnivorous diet, accepting sinking dried foods, vegetables like spinach and kale, as well as live or frozen foods such as bloodworms or daphnia. Ensuring a varied diet is crucial for the health of this species.

Reproduction & Dimorphism

Breeding the Whiptail Catfish is relatively straightforward when provided with proper conditions and nutrition. Male catfish develop odontotes on the head and pectoral rays, distinguishing them from females. Spawning caves made of PVC piping are recommended, with males guarding the fertilized eggs diligently. The fry can be delicate to raise and require constant access to food sources for optimal growth.

Habitat and Distribution

In the wild, the Whiptail Catfish is predominantly found in the Upper Rupununi and Branco River basins in Guyana and Brazil. It inhabits shallow, flowing waters, typically dwelling among leaf litter over sandy substrates. This natural habitat should be replicated as closely as possible in an aquarium setting to ensure the well-being of the catfish.
