FBname: Plains killifish
Comments: Inhabits shallow sandy runs, pools, and backwaters of headwaters, creeks and small to medium rivers.  Tolerates extremely alkaline and saline streams, and often found where few other fishes can survive.  Buries headfirst in sand and orients itself with only mouth and eyes are visible.  This habit may protect the fish from intense sunlight or may help avoid predators, detect potential prey, or stream desiccation.  10 cm max TL (Ref. 5723).  Not a seasonal killifish.  Is easy to maintain in the aquarium (Ref. 27139).
