Rineloricaria Parva

Datasheet

General Description

The Whiptail Catfish, scientifically known as Rineloricaria Parva, is a peaceful species often included in community aquarium setups due to its calm demeanor. It is a common choice for beginners in the realm of Loricariids for its manageable care requirements and compatibility with various tank mates. Proper identification can be challenging, distinguishing true R. parva by dark bands on the body and filaments on the caudal fin.

Aquarium Setup

For a suitable habitat, a biotope setup is recommended, featuring sand substrate layered with dried leaves like oak or beech. Including twisted branches, rounded stones, and rock or wood caves provide enrichment. Alternatively, a well-planted tank can also serve as a comfortable environment for the Whiptail Catfish. Bright lighting should be avoided, and water conditions should be maintained within a pH range of 6.0-7.5, with a temperature of 20-25°C and a hardness of 2-15°dH (see table).

Behaviour

Known for its tranquil nature, the Whiptail Catfish thrives when housed with non-aggressive tank mates like small characins, Corydoras, and other peaceful Loricariids. It tends to be retiring if kept with overly vigorous species and may struggle to compete for food in such environments. While not territorial except during spawning periods, they prefer being in small groups and are not adept at higher temperatures.

Feeding and Diet

In their natural habitat, these catfish feed on aufwuchs and small aquatic crustaceans. In captivity, they exhibit omnivorous tendencies, accepting sinking dried foods, vegetables like blanched spinach and zucchini, and live or frozen food such as bloodworms or daphnia. Ensuring a varied diet rich in nutrients is essential for their well-being.

Reproduction & Dimorphism

Breeding Whiptail Catfish can be relatively straightforward with proper care and diet. Setting up a tank conducive to spawning, including caves for egg deposition, and maintaining water parameters slightly acidic and soft can encourage breeding behavior. Males exhibit odontotes on the head and pectoral rays, distinguishing them from females.

Habitat and Distribution

These catfish are commonly found in Brazil, Paraguay, and Argentina, residing in leaf litter over sandy substrates in clear or whitewater habitats. Whitewater environments are characterized by high sediment content in the water, contrasting with rapid-filled waters.
