Etymology: Poecilia: Greek, poikilos = with a lot of colours (Ref. 45335).
Environment / Climate / Range
Freshwater; brackish; benthopelagic; non-migratory. Subtropical; 27°N - 25°N
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.6 cm TL male/unsexed; (Ref. 5723); common length : 5.5 cm TL male/unsexed; (Ref. 12193)
(total): 10-12. Similar to females of P. latipinna but lacks rows of brown spots on side (may have row of dusky black spots).
North America: lower Nueces River (where possibly introduced) and lower Rio Grande, extreme southern Texas, to Veracruz in Mexico. Introduced populations at San Antonio and San Marcos, Texas.
In backwaters and quiet pools of streams, sloughs, and ditches, usually over mud. This is an all-female species thought to have originated as a result of hybridization between P. latipinna and P. sphenops. Parthenogenesis reproduction is triggered by copulation and stimulation by sperm from either parental species.
