Maturity: Lm ?  range ? - ? cm
Max length : 5.6 cm TL male/unsexed; (Ref. 5723); common length : 3.8 cm TL male/unsexed; (Ref. 12193)
Inhabits margins of spring-fed marsh pools; most common away from vegetation (Ref. 5723). Feeds on diatoms, amphipods, and ostracods (Ref. 79012). Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).
