Identity and locality
Pterygoplichthys joselimaianus (Weber, 1991)
Rio Araguaia / Tocantins basin, Brazil
Diagnostic evidence and naming
Originally described as Glyptoperichthys joselimaianus in 1991. Historical L001 and L022 are trade aliases for one taxon. This is a large sailfin pleco, not the small L-number cave-breeding type.
Breeding and genetics limitations
Avoid prescribing captive spawning protocol from invasive-species literature; record mature size, high waste output and never release captive plecos.
