Hemiodontichthys Acipenserinus

Datasheet

General Description

The Pinocchio Whiptail Catfish, scientifically known as Hemiodontichthys Acipenserinus, is a unique species within the Loricariidae family characterized by its diamond-shaped body when viewed from above and its distinctive knob-nosed rostrum. Being the only species in its genus, it presents a visually intriguing appearance, lacking odontotes on its head and pectoral fins. In its natural habitat of sandy substrates in flowing waters, this species can reach a maximum size of 13.5cm.

Aquarium Setup

For optimal care of the Pinocchio Whiptail Catfish, a tank size of at least 70 liters is recommended, with a setup that includes a soft, sandy substrate to mimic its natural behavior of partially burying itself. Oxygenation is crucial, and water movement aids in maintaining suitable conditions. Decoration such as non-toxic dried leaves (like oak and beach), twisted branches, and rounded stones can be included. Regular water changes are necessary to sustain good water quality in the tank (see table).

Behaviour

Known for its shy and retiring nature, the Pinocchio Whiptail Catfish is easily out-competed for food by more assertive species. It thrives best in the company of small characins, dwarf cichlids such as Apistogramma, and smaller Corydoras. Despite its timid demeanor, this species is usually amicable with conspecifics, allowing a few to coexist in tanks of various sizes.

Feeding and Diet

Being omnivorous, the Pinocchio Whiptail Catfish primarily feeds on aquatic invertebrates in its natural habitat. In aquariums, their diet should consist of live and frozen foods like bloodworms, daphnia, and chopped earthworms. Supplementing with dried sinking foods and occasional vegetables like cucumber or courgette ensures a balanced diet for these captivating catfish.

Reproduction & Dimorphism

Breeding the Pinocchio Whiptail Catfish in captivity is achievable but not common. Acquiring a small group to increase the chances of forming a breeding pair is advisable. Spawning is signaled by male mouthpart enlargement, with the male carrying the eggs in his lower lip post-spawning. Successful incubation and raising of the fry involve attentive care, consistent feeding, and maintaining stable water conditions.

Habitat and Distribution

The Pinocchio Whiptail Catfish is found exclusively in regions of Guyana, French Guiana, Peru, Bolivia, and Brazil. It inhabits sandy substrates in flowing waters, reflecting its preference for camouflage in its natural environment. Adapting the tank setup to mimic these conditions is crucial for the well-being of this species.
