ขนาด / น้ำหนัก / Age
Maturity: Lm ? range ? - ? cm
Max length : 3.5 cm TL เพศผู้/กระเทย; (Ref. 52193)
เงี่ยงครีบหลัง (รวม) : 0; ก้านครีบอ่อนที่หาง (รวม) : 7 - 9; เงี่ยงครีบก้น: 0; ก้านครีบอ่อนที่ก้น: 11 - 16. Diagnosis: Lacustricola hutereaui is easily distinguished from L. chobensis and L. pygmaeus by the possession of a ventral arm in the posttemporal bone vs. ventral arm absent, a sharp ventral process in the maxilla vs. ventral process absent, retroarticular smaller than anguloarticular ventral arm vs. about the same size, a lachrymal without a posteroventral extension vs. posteroventral extension present, and by a sinuous cleithrum posterodorsal flap vs. flap rounded (Ref. 123968).
Found in small rivers, brooks, swamps and shallow lake parts among vegetated areas (Ref. 3788). Strictly a floodplain or marsh-loving species (Ref. 7248, 52193). Not a seasonal killifish (Ref. 27139). Is difficult to maintain in aquarium (Ref. 27139).
