Identity and locality
Historical trade alias L457 → Chaetostoma sacramento
Pampa de Sacramento, Ucayali drainage, Peru
Historic code / name alias. Compare the canonical named species dossier; this is not an additional described species.
Diagnostic evidence and naming
The formal 2024 paper unites historical L457, L455 and L456 under Chaetostoma sacramento. Spot and fin-mark variations must not be elevated to separate genetic species. The specialist catalog documents L457 as a historical Chaetostoma sacramento alias, not a founder-verified captive strain.
Breeding and genetics limitations
A crossbred appearance or specific breeder creator cannot be inferred from L457 trade labels.
