Absolutely, they will eat Endler's fry. 

Jordanella is a monotypic genus with a diagnostic single spine in the dorsal 
fin. It is restricted to southern Florida. Jordanella floridae, the Florida 
flagfish, is a chunky killifish with a prominent dark mark and characteristic 
horizontal thin green lines on the flank. Larger male with intervening red 
lines, extending into the enlarged dorsal fin. Its nearest relative is the Yucatan 
Garmanella pulchra from low salinity water (Parker and Kornfield, 1995). 
Southern peninsular Florida, the most southerly of American killifishes. The male 
occupies a territory in dense vegetation of ponds and lakes over mud or silt, 
and fans the silt to uncover benthic animals upon which it feeds. With 
maturity, this behavior develops into territorial spawning behavior, as the male 
attempts embraces with females entering his feeding territory (Foster, 1966). 
Easily maintained in fresh water with or without salt, and spawned in bare 
aquariums with spawning mops (Smith, 1973), especially on the bottom (Isgro, 1982). 
The fish does better in a larger aquarium with Nitella or Ceratophyllum and 
strong light with a 14 hour photoperiod. Best egg production should be with 1 fish 
per gallon in large (50 gallon) tanks. The vegetation can be transferred to 
another tank for hatching, or fry can be removed when seen at the surface. The 
Florida flagfish requires heat. Its fecundity, ease of breeding, and complex 
behavior make it a good animal for aquatic toxicity studies (Foster, 1969).
