Identity and locality
Pterygoplichthys pardalis (Castelnau, 1855)
Amazon basin South America; wild-caught origin must be validated
Diagnostic evidence and naming
L021 and L023 are hobby codes for one scientifically described sailfin catfish. In invasive populations belly spotting sometimes overlaps with P. disjunctivus, so do not identify hybrids or aquarium strains by a photograph alone.
Breeding and genetics limitations
Large mature body and waste output need planning; never release unwanted aquarium fish into local waterways.
