Species boundary
Poecilia wingei, the Endler's livebearer, is a distinct described species. It readily hybridizes with Poecilia reticulata; dealer labels and color alone do not establish purity.
Line provenance
Store capture locality, original collector or responsible breeding source, introductions, parent records and documented hybridization. Mark guppy-Endler mixes as hybrids rather than documented wild-origin pure lines.
