Identity and locality
Domestic Ancistrus cf. cirrhosus-type yellow bristlenose (pedigree unresolved)
Domesticated trade; origin and founding breeder not firmly documented
Diagnostic evidence and naming
The modern yellow/blue-eye domestic Ancistrus marketed as L144 differs from the original Paraguayan fish in pattern/fin tips/size. One reported mitochondrial DNA match to domestic bristlenose supports only maternal ancestry, not a complete pedigree; founder origin remains unresolved. A specialist Ancistrus monograph's public breeding-form profiles distinguish modern yellow/black-eyed or blue-eyed aquarium stock from the original rare Paraguayan L144. Trade names overlap and yellow appearance alone is insufficient for genetic origin, identity, or a true L144 pedigree.
Breeding and genetics limitations
Require parent identities, segregating F1/F2 crosses, breeder history and phenotypic photos before asserting dominant/recessive inheritance in any specific store line.
