Identity and locality
Panaque schaeferi (Lujan, Hidalgo & Stewart, 2010)
Upper Ucayali, Peru
Diagnostic evidence and naming
A large royal-type Panaque formally named in 2010, known historically as L203 / LDA065. Do not classify as the same species as royal L190 solely on appearance. The 2010 original revision records P. schaeferi from the upper Amazon in Brazil and Peru and describes large spotted adults, not a novel captive color-lineage.
Breeding and genetics limitations
Large body size and strong feeding needs call for dedicated space; original breeder line, spawn success and genetics not established.
