Overview
Pterygoplichthys joselimaianus is a sailfin pleco of the family Loricariidae and subfamily Hypostominae. It is one of the original L-numbered species, traded as L001 (also L022). The body is dorsoventrally flattened and dark brown with light golden spots covering the body and fins; the large dorsal fin has ten rays. It is frequently confused with P. pardalis and P. gibbiceps.
Taxonomy
- Family: Loricariidae
- Subfamily: Hypostominae
- Genus: Pterygoplichthys
- Scientific name: Pterygoplichthys joselimaianus
- Trade code: L001 (also L022)
Habitat
The species is endemic to Brazil, occurring in the Tocantins River basin.
Tank requirements
- Minimum tank volume: 500 L
- Temperature: 26-29 °C (79-84 °F)
- pH: 6.5-7.5
- GH: 2-12 °dGH
- Water flow: moderate, well-oxygenated
- Adult size: up to about 38 cm SL
- Lifespan: about 8-12 years
Given its large adult size and high waste output, this species needs a spacious tank with strong filtration and driftwood.
Diet
It is an omnivore. A predominantly plant-based diet with occasional protein foods suits the species; feeding once daily is appropriate. It is not reliably plant-safe in heavily planted aquariums.
Compatibility
Peaceful and bottom-dwelling, it can share a large tank with robust mid-water fish such as tetras and with corydoras. Other territorial plecos are best avoided.
Breeding Pterygoplichthys joselimaianus (L001)
Overview
Pterygoplichthys joselimaianus (C. Weber, 1991), the Gold Spot Sailfin Pleco (L001), is a large armoured catfish endemic to Brazil in the Tocantins River basin, growing to around 38 cm (15 in) and recorded at 26-29 C with pH 6.5-7.5 (Wikipedia).
Spawning Behavior & Trigger
The species uses a polygamous mating system in which males establish and defend territories and prepare burrows or caves in riverbanks or substrate. They excavate a deep tunnel in muddy banks where the eggs are deposited and develop.
Common Challenges
Home aquaria cannot provide the deep, excavatable muddy banks, river-scale space and seasonal cues this species depends on for reproduction, which is why no aquarium spawning has been reported. Owners should focus on long-term care of this large, long-lived pleco rather than breeding.
