features
Labidesthes sicculus is slender and elongated, the mouth is terminal. The fish are almost transparent with a light olive-green back. The scales on the back side have dark edges, creating a mesh pattern. A narrow, black stripe extends between the first and second dorsal fin and on to the caudal peduncle. The sides of the body, the gill cover and the underside of the head are silvery-white and have iridescent blue-green spots. The underside of the lower jaw is black. On the flanks there is a silvery band that narrows towards the back and is often underlaid with black pigments. Sexually mature fish have yellow to orange fins and a red mouth. The intestine is short and curved in an S-shape. The ratio between the length of the intestine and the total length is 0.5.
