Etymology: Fundulus: Latin, fundus = bottom; a peculiar name for a topminnow, coined for a bottom species of Atlantic coast being "the abode of the fundulus mudfish" (Ref. 45335); julisia: Derived from the Cherokee amjulisi atsat meaning watercress fish (Ref. 10294).

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.0 cm TL male/unsexed; (Ref. 27139)
North America: upper Caney Fork (Cumberland River drainage) and upper Duck River (Tennessee River drainage) systems in central Tennessee, USA.
Occur in vegetated pools and margins of springs and spring-fed headwaters and creeks (Ref 5723, 10294). 9.4 cm TL (Ref. 5723).
