Etymology: Labidesthes: Greek, labidos = pair of forceps + Greek esthio = to eat; in reference to the shape of the mouth (Ref. 45335); sicculus: Name most likely from Latin 'sicula' meaning small dagger (see Ref. 104856). Others consider the origin of the name from the Latin 'siccus' meaning dried, referring to being found in dried pools (Ref. 10294, 79012).

背棘 (总数) : 4 - 7; 背的软条 (总数) : 8 - 12; 臀棘: 1; 臀鳍软条: 19 - 27. This species is distinguished and differs from Labidesthes vanhyningi by the following characters: Labidesthes sicculus have the anterolateral processes of the posttemporals longer than width of the base (vs. L. vanhyningi having the processes shorter than width of base); with a midlateral stripe tapering to insertion of pectoral fin in advance of first dorsal fin (vs. maintaining width or usually expanding, to insertion of pectoral fin in advance of the first dorsal-fin); a ratio of thoracic length to abdominal length greater than 2 (vs. less than 2) (Ref. 104856).
Body shape (shape guide): elongated; Cross section: compressed.
Body shape (shape guide): elongated; Cross section: compressed.
Adults occur near surface of lakes, ponds, and quiet pools of creeks and small to large rivers. Usually found in open water (Ref 5723, 10294). They feed on zooplankton, including copepods, cladocerans, and midge larvae (Ref. 10294).
出现近表面的小溪与小型到大型河川的湖，池塘与静止的池水。 通常发现于开放水域。
