Papa Lyretail Plecostomus - Panaque bathyphilus : Complete Fish Profile & Care Guide
Table of contents
Introduction
Papa Lyretail Plecostomus (Panaque bathyphilus), often overlooked in the vast realm of aquatic species, is a remarkable freshwater fish that belongs to the Loricariidae family. Hailing from the deep waters of South America, this species distinguishes itself through its unique morphology and ecological adaptations. As part of the "wood-eating" catfish genus, these Plecos possess specialised spoon-shaped teeth, enabling them to efficiently graze on submerged wood, making wood not just a habitat but also a crucial component of its diet. While still relatively understudied, this species offers a captivating subject for aquarists and ichthyologists keen on exploring the nuanced behaviours and requirements of less mainstream freshwater species.
The Papa Lyretail Plecostomus is typically characterized by its serene demeanour, though it may display territorial inclinations towards its own species and similar counterparts. Co-housing multiple individuals within a singular tank setting is feasible, provided ample space is accompanied by numerous concealment areas and visual partitions. Compatibility-wise, this Pleco aligns well with medium-sized characins, selected resilient Corydoras catfish varieties, and a spectrum of rheophilic cichlids. However, due to their distinct elongated tail filaments, believed to function in predator detection and environmental sensing, they should not be paired with fin-nipping species.
Accommodating their considerable growth trajectory, these Plecos necessitate an expansive, seasoned aquarium environment infused with soft, acidic water. Optimal conditions would incorporate muted lighting, a deep-hued substrate, and a plethora of shaded havens amidst bogwood and robust rock caverns. It's imperative to secure all decorations, given the occasional awkward manoeuvres of the larger specimens. Regrettably, even the most resilient aquatic plants may fall prey to their grazing habits. Given the considerable waste generated by matured specimens, advanced filtration and a pronounced current, achieved through supplementary powerheads, are indispensable. Such conditions emulate their native oxygen-rich water habitats, with stagnant environments being detrimental. Periodic partial water replacements are essential to maintain minimal levels of nitrogenous byproducts.
In terms of colouration, two distinct variants are discernible: a traditionally pigmented morphology and an albinistic type devoid of melanin, perceived as an evolutionary nuance to their shadowy ecosystems. Among the larger Panaque varieties, it arguably stands out for its marbled interplay of dark stripes and its signature lyre-shaped tail, which often features extended white caudal extensions. Its petite eyes further define its identity. Its caudal fin may adopt a subtle orange hue when nurtured with a diet rich in beta-carotene.

Sexual Dimorphism
The Papa Lyretail Plecostomus exhibits distinct sexual dimorphism, which aids in differentiating between male and female specimens. Typically, mature males display more prominent and pronounced odontodes, especially along the edges of the pectoral fin spines and on the posterior section of the body. These specialized, tooth-like structures play a crucial role during the breeding season, offering an advantage in territorial disputes and courtship rituals.
In contrast, females often possess a fuller, more rounded body shape, particularly in the abdominal region, which facilitates the carrying of eggs. When viewed from above or in profile, these differences in body contour can be discernible. However, accurate identification, especially in younger specimens, might still require close observation and comparison, given the subtleties of these morphological differences.

Natural Habitat
The Papa Lyretail Plecostomus is native to the rapid white water stretches of the upper Rio Marañón, Rio Ucayali, and Rio Huallaga in Peru, as well as the Rio Solimões in Brazil. Within these regions, it inhabits the profound depths of primary river channels, typically taking refuge beneath submerged trees and entangled wood, where it exists in near-complete obscurity.
Breeding
Breeding the Papa Lyretail Plecostomus in a controlled environment poses a unique set of challenges, largely due to the species' specialized natural habitat and specific requirements. Native to the deep freshwater regions of South America, this particular species thrives in conditions that replicate the cooler, oxygen-rich, and fast-flowing waters of its native habitats.
To encourage breeding, aquarists must ensure the availability of submerged wood, not just as a dietary requirement but also to provide ample shelter and egg-laying sites. Providing caves or suitable recesses is equally important as they tend to lay their eggs in hidden, protected environments. Maintaining pristine water quality, replicating their natural diet, and ensuring that there are minimal disturbances in the breeding tank are pivotal for successful spawning.
While breeding this species in captivity remains relatively rare, the continuous study and replication of their natural environment could pave the way for increased success in the future.
Diet & Feeding
The Papa Lyretail Plecostomus, like the majority of the Panaque species, predominantly feeds on wood, making the inclusion of bogwood in their aquarium habitat imperative. It is recommended to provide a diverse diet, with a significant emphasis on vegetable-based foods such as courgette, cucumber, lettuce, potato, pumpkin, squash, spinach, and sweet potato, all of which they readily accept. While sinking wafers/tablets can be introduced as supplements, occasional offerings of protein-rich foods like bloodworms or chopped prawns can also be considered. Notably, these fish possess an elongated digestive tract specifically designed to process foods with high vegetable content. Thus, it's crucial to moderate the intake of protein-rich foods to avoid potential health issues.
