Scarlet Cactus Plecostomus - Pseudacanthicus pirarara : Complete Fish Profile & Care Guide
Table of contents
Introduction
Scarlet Cactus Plecos (Pseudacanthicus pirarara) enjoy a distinguished status as one of the most coveted and captivating Pleco species, commanding global recognition. As they progress through their life stages, these specimens undergo a remarkable transformation, evolving into substantial and territorially assertive foragers, eliciting both fascination and admiration from dedicated enthusiasts capable of accommodating their unique requirements.
Analogous to numerous other Pleco species, they exhibit a generally peaceable disposition when afforded the requisite space to establish and safeguard their territorial domains, vehemently defending against potential intrusions from other fish species. However, a proclivity for heightened aggression surfaces in interactions with conspecifics or Plecos of analogous appearance, particularly when confined within confined confines. Coexistence with other sizable, robust species, such as Red Shoulder Severum, Striped Silver Dollars, and Peacock Bass, is feasible and considered compatible.
To maintain the thriving condition of Scarlet Cactus Plecos, meticulous adherence to specific environmental parameters is paramount. Creating an emulated riverine habitat entails the incorporation of a substrate comprising rocks, sand, fine gravel, and strategically positioned water-worn boulders. The establishment of a suitable refuge system encompassing driftwood branches, terracotta pipes, plastic conduits, and plant pots serves the dual purpose of delineating territorial boundaries and offering an intricate network of concealed spaces conducive to their well-being.
This particular species exhibit a pronounced preference for subdued or low-light environments, aligning with its natural proclivities.
Moreover, ensuring optimal water quality is of paramount importance, necessitating the integration of a robust filtration system, adequate oxygenation, and the implementation of regular water changes. These measures are fundamental to promoting the thriving condition of Scarlet Cactus Plecos within the confines of the aquarium.
Scarlet Cactus Plecos showcase a striking aesthetic, characterized by dark brown bodies adorned with jet-black spotting and accented by deep red-orange fin tips. These plecos notably feature prominent spines along their pectoral, dorsal, and caudal fins, enhancing their unique allure. It is worth noting that the colours and their intensity can exhibit slight variation, influenced by the specific locale within the Xingu delta from which they have been collected.

Sexual Dimorphism
Discerning the gender of Scarlet Cactus Plecos is a straightforward process facilitated by readily distinguishable sexual traits. Males are characterized by their more pronounced and contrasting colouration, accompanied by an enlargement of their fins. Notably, males exhibit an enlarged head, both in terms of length and width, further accentuated by subtly more prominent pectoral fin rays. Conversely, females are readily identifiable by their conspicuously more robust abdominal region, a defining feature indicative of their gender.

Natural Habitat
Scarlet Cactus Plecos are native inhabitants of the Rio Xingu and the Rio Iriri in the state of Para, Brazil, situated within the continent of South America. In their natural habitat, these Plecos predominantly occupy regions characterized by the presence of briskly moving, warm waters distinguished by their clarity and soft composition. The substrate of their aquatic environment commonly consists of a mosaic of pebbles, woody debris, or drifting leaves, all influenced by the prevailing currents. Notably, these Plecos tend to congregate in close proximity to cascading waterfalls within their habitat.
Breeding
Scarlet Cactus Plecos exhibit distinctive breeding behaviours in the context of aquaculture. The process of breeding this species is a multifaceted and intricate endeavour, primarily attributed to the limited availability of documented knowledge in this regard.
Successful breeding necessitates a profound understanding of their native habitat, thereby involving the meticulous recreation of a riverine ecosystem within the confines of an aquarium. In captivity, these plecos thrive within spacious enclosures replete with an abundance of appropriate hiding locations, including driftwood, caves, and terracotta pipes.
The breeding pair, often discerned through their sexual dimorphism, is required to establish a secure territorial domain conducive to spawning. During the courtship phase, males exhibit territorial behaviours and may manifest heightened aggression. The spawning process typically entails the female depositing eggs, which the male subsequently fertilizes and vigilantly guards.
The pivotal aspects of successful breeding encompass the meticulous care and nourishment of the larvae, demanding meticulous attention and the provision of suitable sustenance to ensure their progressive growth and ultimate survival. Overall, the breeding habits of Scarlet Cactus Plecos underscore the intricate nature of their reproduction, highlighting the imperative need for expertise and precise husbandry practices.
Diet & Feeding
The dietary requirements of Scarlet Cactus Plecos prioritize protein-rich sources, with mussels and shrimp standing as highly preferred selections. To maintain their optimal nutrition and well-being, it is recommended to supplement their diet with dry foods containing a significant vitamin content. This approach ensures a comprehensive and nutritionally balanced feeding regimen tailored to their specific needs.
