Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 27139); common length : 2.9 cm TL male/unsexed; (Ref. 12193); max. reported age: 2 years (Ref. 12193)
Inhabits vegetated sloughs, ponds, lakes, and pools and backwaters of streams. Often common near springs. Usually swims well below surface of water (Ref. 5723). Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139).
