Identity and locality
Domestic Ancistrus line (Longfin)
Captive/hobby origin; locality and initial founder unverified
Diagnostic evidence and naming
Fin-length selection in domestic Ancistrus, not a distinct wild L-number or standalone species. Common domestic bristlenose stock is often taxonomically unresolved; do not automatically label it Ancistrus dolichopterus or assign L144. A specialist common-bristlenose account and a separate breeder-form overview record longfin/veiltail domestic Ancistrus that can coexist with color morphs. A dominant fin-length allele or universal F1/F2 ratio is not validated for every longfin lineage by these sources.
Breeding and genetics limitations
Requested evidence: named parent pair, breeder identity, F1/F2 outcomes, hatch dates, phenotype photographs, number of generations and selection criteria.
